Abstract

The effects of removal of Pb(Ⅱ)from raw water with hydrated manganese dioxide produced by reduction of KMnO4 are studied by coagulation experiments.The effects of pH value and humic acid of raw water on removal of Pb(Ⅱ) are investigated and the possible mechanism are discussed.The results show that the hydrated manganese dioxide has excellent effect of removing Pb(Ⅱ)from raw water.The removal rate of Pb(Ⅱ)reaches 95% with 5 mg/L hydrated manganese dioxide.The removal rate of Pb(Ⅱ)reaches 95% from 70% with 1 mg/L hydrated manganese dioxide as a coagulant aid.So the hydrated manganese dioxide is a kind of effective water treat ment reagent for removing Pb(Ⅱ).
