摘　　要：研究了高铁酸钾对矿井水和模拟水样中重金属的去除效果。结果表明,pH对高铁酸钾去除模拟水样中高浓度的Pb、Cd、Fe、Zn、Mn和Cu有很大影响,去除率随着pH的升高而增加,酸性条件下去除率较低,在pH为10、加药量30mg·L-1时,去除率在56.9%～94.4%之间;当pH为8.3、加药量30mg·L-1时,高铁酸钾能够使矿井水中超标的Pb、Cd和Fe达到国家生活饮用水卫生标准(GB5749-2006),对矿井水中未超标低浓度Mn的去除率为53.7%,而对低浓度的Cu、Zn却几乎没有去除效果。Potassium ferrate （K2FeO4） was used to study the removal of heavy metals in mine water and simulated water samples. The results showed that pH had great influence on removing high-concentration of Pb,Cd,Fe,Zn,Mn and Cu in simulated water samples.The removal rate was continuously increasing with the increasing ofpH but lower in acidic conditions, and 56.9%-94.4% when pH was 10 and the addition amount of potassium ferrate was 30mg·L^-1. When pH was 10 and the addition amount was 30 mgmg·L^-1, potassium ferrate could treat the over standard Pb,Cd and Fe to standards for drinking water quality（GB5749-2006） in mine water, meanwhile, the removal rate was 53.7% to the low concentration and no over standard Mn but rather low to the low concentration Cu and Zn.
