The effect of temperature,initial pH,persulfate concentration and some kind of inorganic ions on the potassium persulfate oxidation degradation of imidacloprid were investigated,and the kinetics of the degradation of imidacloprid were also discussed.Results indicates that the degradation of imidacloprid followed pseudo-first-order kinetics equation. Increasing temperature and oxidant dosage could enhance the removal efficiency of imidacloprid,and the degradation rate of imidacloprid gradually stabilized aft...
