Removal of MC-LR in Micro Polluted Water under Different Treatments

To compare the UV/H2O2,H2O2/Fe2+(Fenton reaction) two experimental method for microcystin-LR degradation,the change of concentration of H2O2 or Fe2+ 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 Fe2+ concentration increases,MC-LR degradation effects were gradually raising,when Fe2+ concentration reached to 1.0 mmol/L,10 mmol/L concentration of H2O2,and degradation for 5 min,MC-LR degradation rate can reach 93%.
