A “cocktail” of solvent, sodium hydroxide (a common ingredient in soap) and water heated to boiling can decompose PFAS compounds.
Scientists have discovered the easiest and cheapest way to remove chemicals from water and soil. with “eternal chemicals”. Representatives of the US Environmental Protection Agency investigated the toxicity of PFAS compounds and found that when in contact with common solvents, the chemical compounds began to decompose, writes Science.
As part of their research, chemists at Northwestern University studied various solvent compounds with other substances. So it was found that a “cocktail” of a solvent, sodium hydroxide (a common ingredient in soap) and water, heated to boiling, was able to decompose PFAS compounds.
However, this method is only suitable for PFAS containing carboxylic acid, which is only 40% of PFAS compounds. However, scientists are optimistic.
It will be remembered that earlier the laboratory of Nagoya University (Japan) professor, Nobel laureate in physics in 2014 Hiroshi Amano developed technology for purifying water with ultraviolet light using LEDs.
