Improved Desalination Process Also Removes Toxic Metals to Produce Clean Water

UC Berkeley chemists synthesized a flexible polymer membrane incorporating nanoparticles called “porous aromatic frameworks.” The membrane selectively absorbs nearly 100% of metals such as mercury, copper, or iron during desalination, more efficiently producing clean, safe water. The membrane can incorporate a single type of tuned nanoparticle if the metal is to be recovered – or several different types, each tuned to absorb a different metal or ionic compound if multiple contaminants need to be removed in one step.
