Polymer Network Captures Drinking Water Contaminant

Long-chain perfluorinated chemicals contaminate millions of Americans’ drinking water. These compounds are a legacy of industrial pollution and the use of firefighting foam at military bases and airports; they persist in the environment because of their strong carbon-fluorine bonds. Now scientists have designed a cross-linked polymer that might more effectively remove one of the more prevalent and harmful of these compounds, perfluorooctanoic acid (PFOA).

PFOA—used to make coatings, including DuPont’s Teflon—was phased out by U.S. manufacturers in 2015 at the request of the Environmental Protection Agency. In humans, epidemiological studies have linked chronic exposure to PFOA with cancer, thyroid disease, high cholesterol, and other health issues, and low levels of exposure with immunotoxicity in children. Studies in animals have additionally linked the compound with negative effects on fetal development.

Structure of perfluorooctanoic acid

The evidence led the EPA in 2016 to set the health advisory level in drinking water at 70 ppt for PFOA and a related chemical, perfluorooctanesulfonic acid (PFOS), individually or in combination. However, some researchers suggest safe levels may be 1 ppt and below. The two chemicals have been found at levels over 20 ppt in 162 drinking water systems used by about 15 million people in 27 U.S. states, according to a recent report by the nonprofit Environmental Working Group and Northeastern University.

To purge these perfluorinated chemicals from water, engineers primarily use granular activated carbon as an adsorbent. But the material has limitations. “Almost anything organic sticks to it,” including other pollutants and components of natural organic matter, such as humic acid, says William R. Dichtel of Northwestern University. Once that happens, the activated carbon usually needs to be replaced. And the material does not have particularly high affinity for PFOA, so it’s inefficient at trapping the pollutant. Other options for removing these compounds include reverse osmosis, which is much more expensive than activated carbon, and anion-exchange resins, which are still at the experimental stage for this application, according to Christopher P. Higgins, an environmental engineer at the Colorado School of Mines.

Now Dichtel, Damian E. Helbling of Cornell University, and colleagues have developed an alternative adsorbent: a cross-linked cyclodextrin polymer with much higher affinity for PFOA than activated carbon. It also tends not to clog up with humic acid and can be regenerated with a methanol rinse.

β-Cyclodextrin—made of a ring of seven glucose molecules—has an inner hydrophobic pocket that is the right size to trap hydrophobic micropollutants such as pesticides and pharmaceuticals. Cyclodextrins have been studied as water purification agents and are used in the product Febreze to trap odor compounds.

Dichtel’s group previously made polymers of β-cyclodextrin by incorporating rigid aromatic cross-linkers; the resulting high-surface-area material could trap a wide range of micropollutants. But this system didn’t capture PFOA well. So they tweaked it using a cross-linker containing multiple fluorines—a decafluorobiphenyl group—counting on the tendency of fluorinated substances to stick together.

The researchers tested the polymer by adding it to water at 10 mg/L with 1 ppb PFOA, a level similar to that found in contaminated groundwater near some former industrial sites. The polymer removed more than 99% of the PFOA, bringing its concentration down to less than 10 ppt, below the EPA’s health advisory level. In comparison, activated carbon removed only 56% of the PFOA.

The researchers still have to design a practical system to continuously treat water with the soluble polymer, possibly by attaching the material to a solid substrate like a cloth or filter. Dichtel and others have started up the company CycloPure to develop and commercialize the technology. The polymer would likely cost more than activated carbon by weight, Dichtel says, “but the idea is that we will be able to use less and regenerate our polymer.”

Higgins, who was not involved in the study, calls it “really important,” especially if it can be adapted to treat other compounds like PFOS—something the team is now testing. “It’s certainly going to help us move forward with alternative technologies for water treatment of these compounds,” he says.

Higgins notes that he has some reservations about the method’s use of one highly fluorinated material to clean up another, because of the chance that the adsorbents themselves could contaminate the environment. However, he adds, water treatment facilities would have control of these adsorbent materials, and their aromatic fluorinated structure would be easier to treat and break down than PFOA if they were accidentally released.

Sunlight Surprise Raises Cadmium Pollution Risk

Even though cadmium is considered a probable human carcinogen by the U.S. Environmental Protection Agency, it is still used to give some plastics and ceramics red, orange, or yellow hues. That’s because organic pigments are unstable at the high temperatures used to make these products, and pigments like cadmium red are thought to be relatively inert in the environment on account of their reportedly low solubility in water.

That belief has been turned on its head by a new study showing that in sunlight, a commercially available cadmium red pigment rapidly dissolves in water, releasing the toxic metal.

Some experts say the findings probably do not indicate additional risk for exposure to cadmium in consumer products. Still, the study suggests that dumping of cadmium red pigment into waterways could pose a much greater risk of contamination than has previously been thought.

Xiaolei Qu of Nanjing University and his colleagues were investigating the causes of cadmium contamination in farmland near China’s Lake Tai (often called Lake Taihu). The area’s large ceramics industry uses cadmium pigments, so the researchers wondered if the pigment might be the source of the cadmium in the soil. But the presumed low solubility of the pigment seemed at odds with this idea.

From their previous work in photochemistry, however, the researchers also knew that light can react with the salts used in cadmium red pigment—cadmium sulfide and cadmium selenide. These semiconductor compounds were once proposed for use in solar cells, but were largely rejected because light oxidizes the salts in the presence of oxygen and water, generating sulfate and selenate ions. For similar reasons, cadmium pigments in oil paintings have faded over hundreds of years, forming hydrated cadmium sulfate and other cadmium salts (C&EN, February 1, 2016, page 32).

Qu and colleagues thought that if these reactions happened in an aqueous environment, the light-driven reactions might release the Cd2+ ion, allowing it to dissolve. This chemistry could allow any pigment released into waterways to end up in nearby soil. So they tested a sample of the pigment from a commercial supplier in China.

They mixed the pigment powder into a 1 mM sodium chloride solution, to simulate the ionic strength of river water, and incubated samples in simulated sunlight and darkness. They tracked the cadmium ion concentration in the water over time with atomic absorption spectroscopy. The researchers found that 83% of cadmium in the pigment dissolved in water under simulated sunlight conditions in 24 hours, compared with less than 3% in the dark. They also mixed the pigment with a sample of river water and exposed it to sunlight; there, 39% of the cadmium was released into the water within four hours.

The rapid dissolution of the pigment in these conditions is an important finding, according to Keith Vorst of Iowa State University; it’s especially relevant in cases in which the pigment may be dumped directly into the environment.

However, Vorst and his colleague Greg Curtzwiler, who study hazardous metals in consumer plastics and packaging at Iowa State’s Polymer and Food Protection Consortium, say this phenomenon would be unlikely to enhance leaching of cadmium from intact plastics or ceramics colored with the pigment, because the pigment is locked into the solid polymer or ceramic. Qu and colleagues are now testing whether cadmium is released from various consumer products when exposed to sunlight. He says that regulators should take photochemistry into consideration when managing the disposal of cadmium pigment waste and its use in products.

In the U.S., regulations on cadmium in consumer items vary by product type. The FDA regulates the amount of cadmium that leaches from imported and domestic ceramics in acetic acid. The Model Toxics in Packaging Legislation, adopted by 19 U.S. states, prohibits the intentional use of cadmium, lead, mercury, and hexavalent chromium in packaging, and limits incidental amounts of these metals. In children’s toys, soluble cadmium in paints and coatings is limited to 75 ppm. In 2010, several consumer and environmental groups petitioned for tougher cadmium standards after high-profile recalls of children’s products containing the element, but the Consumer Product Safety Commission rejected the petition, arguing that the current standards were adequate.

How to Get More Out of Chemistry Networking Events with ACS on Campus

ACS on Campus has been around the world in 2017. From Pune to San Francisco to Taipei City, the American Chemical Society’s premier outreach program continues to bring the leaders in chemistry, publishing, research, science communication and career development to university campuses to help students and emerging researchers advance in their careers.

Whether you’re attending an event at your school or halfway around the world, follow these tips to make sure you get the most out of your chemistry networking event.

  • Practice your elevator pitch: You’ve got less than a minute to make a good first impression, so make each second count with a well-honed elevator pitch. Explain your work succinctly, focus on the impact of your research, and leave room for the other person to ask questions.
  • Have business cards handy: Once you’ve landed the perfect impression, make it easy for your new contacts to follow up with you after the event. Your work may have provided you with business cards or you may have a small batch printed for your personal use. Either way, keep them close at hand during the event – and be sure to ask for you new acquaintance’s card in return.
  • Do your groundwork: You’ll get more out of an event’s speakers if you’ve read up on their background ahead of time. Familiarize yourself with their work before the event, so you can ask intelligent questions and make a strong impression.
  • Show up ready to work: Sessions on manuscript preparation are always a hit at ACS on Campus events. Come with a project in mind so you can begin to apply these tips right away.
  • Connect on social media: Scientific networking events usually have their own hashtags on social networks such as Twitter and Instagram. Use these feeds to join the conversation and add another layer to your networking strategy.
  • Register early: Events fill up quickly – and so does your schedule. Be sure to register to attend events early so that important networking opportunities don’t pass you by.

A Perspective on Sparingly Solvating Electrolytes for High Energy Density Lithium–Sulfur Batteries

Moving to lighter and less expensive battery chemistries compared to contemporary lithium-ion requires the control of energy storage mechanisms based on chemical transformations rather than intercalation. Lithium–sulfur (Li/S) has tremendous theoretical specific energy, but contemporary approaches to control this solution-mediated, precipitation–dissolution chemistry require large excesses of electrolyte to fully solubilize the polysulfide intermediates. Achieving reversible electrochemistry under lean electrolyte operation is the most promising path for Li/S to move beyond niche applications to potentially transformational performance. An emerging Li/S research area is the use of sparingly solvating electrolytes and the creation of design rules for discovering new electrolyte systems that fundamentally decouple electrolyte volume from sulfur and polysulfide reaction mechanism.

This Perspective video, based on an article in ACS Energy Letters, presents an outlook for sparingly solvating electrolytes as a key path forward for long-lived, high energy density Li/S batteries including an overview of this promising new concept and some strategies for accomplishing it.
