采用Fe-TAML/H2 O2催化氧化工艺，实现了杀螟松和其它两种有机磷农药的溶液完全降解。降解产物已被确定和量化，为氧化水解、氧化脱硫、过水解和深度氧化提供了证据。可通过pH控制选择降解途径，以完全消除所有有毒残留物。水生毒性试验支持降解过程的环境相容性。
A Fe-TAML/H2O2catalytic oxidation process achieves facile in-solution total degradation of fenitrothion and two other organophosphorus (OP) pesticides. Degradation products have been identified and quantified providing evidence for oxidative hydrolysis, oxidative desulfuration, perhydrolysis, and deep oxidation. Degradation pathways can be selected by pH control to completely obviate all toxic residuals. Aquatic toxicity assays support the environmental compatibility of the degradation process.
