Mono- and tri-vanadium-substituted Keggin-type heteropolyoxoanions [SiW12O40]4- and[PW12O40] 4- were evaluated as photocatalysts for the photodegradation of three hazardous food pesticides: Atrazine, Chlorpyrifos and Dieldrin. Kinetic experiments were performed under UV irradiation at 254nm. The degradation of each pesticide was assessed by investigating its disappearance with time using High Performance Liquid Chromatography c o n n e c t e d to an Ultra-Violet s p e c t r o p h o t ome t e r d e t e c t o r (HPLC-UV). The photocatalytic degradation of the three pesticides exhibited first order kinetics. It was …
