Hydrolysis of Pesticides in Wastewater Catalyzed by Cu(II) Complexes of Silyl Based Cationic Micelles

摘要

The effect of cationic surfactant micelles, namely hexadecyl trimethyl silane ammonium chloride (A), dodecyl trimethyl silane ammonium chloride, (B) and their copper (II) ion complexes on the hydrolysis of the pesticides: diazinon, cypermethrin, and carbaryl was studied. The rate of the pesticides decay in water was significantly accelerated in presence of these cationic micellar solutions. Furthermore, the copper (II) ion complexes of these micellar were found to be much more effective in hydrolysis of these pesticides. The results indicate that the complexes with a 1:1 ratio of both ligands to the metal ions are the active species in catalytic hydrolysis of carbaryl pesticide. Kinetic study is explained.
