Photodegradation of Humic Acid and its Effect on the Property of Copper Binding

Abstract:

Humic acid plays an important role in regualting the physical, chemical and biological properties in aquatic systems. In this paper, photochemical degradation of humic acid and its effect on the copper binding coefficient were studied. Results showed that the copper binding coefficient decreased with increased irradiation time. The decrease of copper binding coefficient was significantly correlated with the humic acid structure parameters (SUVA270 and E2/E3) during the photodegradation. It suggested that photodegradation of humic acid may have effects on the bioaccumulation of copper and hence its toxicity to aquatic organisms.
