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.
