Photochemical behaviors of mercury (Hg) species in aquatic .

The photochemical reaction of Hg 2+ with thioglycolic acid (TGA, HSCH 2 COOH, an important thiol in the aquatic environment) was studied by Si and Ariya (2015) for the first time. It was found that when the Hg 2+ /TGA molar ratio > 1 at acidic pH, the aqueous TGA reacts with Hg 2+ ions to form Hg(OOCCH 2 S) complex, and the photolysis of the .
