| 摘 要： | 本研究采用过一硫酸盐降解有机磷农药毒死蜱，系统地考察了降解过程的动力学、降解产物、降解机制及其生态毒性风险.结果表明，过一硫酸盐能有效降解水溶液中的毒死蜱.过一硫酸盐降解毒死蜱的体系中起作用的不是SO4·-和·OH等活性自由基，而是过一硫酸盐本身.提高过一硫酸盐投加量会促进毒死蜱的降解；碱性条件有利于其去除过程；离子强度的升高会抑制毒死蜱的降解；腐殖酸的存在也会抑制毒死蜱的降解，但其仅在高腐殖酸浓度时呈现明显的抑制作用.产物鉴定表明，过一硫酸盐直接降解毒死蜱主要有去乙基化、PS的氧化和C—O的断裂3条途径.经ECOSAR生态毒性模型预测发现毒死蜱的降解产物对鱼、水蚤和绿藻的生物毒性均低于毒死蜱母体.研究表明，过一硫酸盐可以作为水处理中降解毒死蜱的有效手段，为去除水体中毒死蜱的实际应用提供了可行性依据.
