| Abstract: | The influencing factors of MC-LR oxidation and degradation by Fenton method were investigated, including reaction time, pH, H202 concentration, Fe2＋/H202 molar ratio, Fe3＋ etc. The orthogonal experiment results showed that the capability of effect factors was H2 02 concentration 〉 Fe2＋ concentration 〉 reaction time 〉 pH. The optimum conditions were： the H202 concentration of 1. 8 retool/L, 1 ： 18 of Fe2＋/H202, the initial pH value of 3, reaction time for 30 rain and the reaction temperature of （25 ＋ 1 ） ℃. The removal rate could be 94.4% under these conditions when the initial concentration of the MC-LR was 2.0 μg / L. |
