| Abstract: | Chlorpyrifos(CP) is one of the most widely used organophosphorus pesticides in the world,of which photodegradation is primary degradation pathway in the environment.Photodegradation mechanism of chlorpyrifos under microwave-assisted electrodeless discharge mercury lamp(MW-EDML) in aqueous solution was studied and degradation products were identified by LC-MS.Additionally,B3LYP/6-31G(d) of density functional theory method(DFT) of quantum chemistry was used to compute parameters of chlorpyrifos and the relati... |
