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.

Improved Desalination Process Also Removes Toxic Metals to Produce Clean Water
-Adapted from UC Berkeley news release by Bob Sanders
Desalination - the removal of salt - is only one step in the process of producing drinkable water, or water for agriculture or industry, from ocean water or wastewater. Either before or after the removal of salt, the water often has to be treated to remove boron, which is toxic to plants, and heavy metals like arsenic and mercury, which are toxic to humans. Often, the process leaves behind a toxic brine that can be difficult to dispose of.
