| Abstract: | A doping system (Ag/ZnO ) for photocatalytic degradation of methylparathion (MP) aqueous solution is described. It is found that the system has the ability to degrade MP effectively by way of irradiation of UV rays.The various factors that influence the photocatalytic degradation of MP have been studied. A preliminary discussion of the photodegradation mechanism and kinetics is made. The MP initial degraded products are C2H6P+S and O2NC6H4O-. The order of MP decomposition reaction is one and its half-lived time (t1/2) is 1. 82 min. |
