The results showed that both increasing the KMnO4 concentration and using acidic or alkaline solution promoted the removal of Hg^0. The reasons are that H2SO4 in solution facilitates the adsorption of Hg^0 on MnO2, and that free radical OH produced in alkaline solution can oxidate Hg^0. High temperature has a negative effect on the removal of Hg^0, and the effect of Hg^0 initial concentration can be neglected.

研究结果表明，高猛酸钾初始浓度的增加、强酸或强碱条件均有利于Hg^0的去除，H2SO4的存在促进了Hg^0在MnO2上的吸附，而强碱水溶液中产生的OH间接氧经了Hg^0；反应温度的升高抑止了Hg^0的去除，而Hg^0初始质量浓度对反应的影响可忽略；KMnO4。
