Abstract:

To explore the new way of organophosphorus pesticides degradation, according to the weight proportion of 9:4:3:2, Rheum palmatum L., Aralia chinensis L., Hibiscus syriacus Linn., Rhus chinensis Mill. were mixed, then smashed into the powder which was soaked with water for the experiments. Using the GC-MS method and fast testing method for pesticide residues, the degradation effect of organophosphorus was clarified by comparing the concentration dynamics of the pesticides. The results showed that the degradation rates of chlorpyrifos and thiophos in 2 minutes were respectively 93.6% and 92.9%. The degradation rate of dichlorvos in 17 hours was 66.67%, and the rate of chlorpyrifos in 11 hours was 48.69%. The experiments showed that leaching solution of Rheum palmatum L., Aralia chinensis L., Hibiscus syriacus Linn., Rhus chinensis Mill. had significant degradation effect on organophosphorus pesticides, such as chlorpyrifos, thiophos and dichlorvos.
