摘　　要：比较了UV/H2O2,H2O2/Fe2+(Fenton反应)两种实验方法对微囊藻毒素-LR的降解效果,通过改变H2O2浓度或者Fe2+浓度,寻找微囊藻毒素-LR最佳降解效果。实验表明,UV/H2O2条件下随着H2O2浓度的增加,微囊藻毒素-LR降解效果先增加后减少。在Fenton体系中H2O2或Fe2+浓度的增加,MC-LR降解效果均逐渐上升,当Fe2+浓度为1.0 mmol/L,H2O2浓度为10 mmol/L时,降解5 min,MC-LR降解率能达到93%。To compare the UV/H2O2, H2O2/Fe^2＋ （Fenton reaction） two experimental method for microcystin -LR degradation, the change of concentration of H2O2 or Fe^2＋ concentration was investigated to looking for the best degradation effect of microcystin - LR. The experiments show that, using UV/H2O2 conditions with increasing concentration of H2O2, microcystin -LR degradation effect first increased and then decreased. In Fenton system H2O2 or Fe^2＋ concentration increases, MC -LR degradation effects were gradually raising, when Fe^2＋ concentration reached to 1.0 retool/L, 10 mmol/L concentration of H2O2, and degradation for 5 min, MC -LR degradation rate can reach 93%.
