摘要

The reduction of manganese dioxide withammonium sulphite in the presence of Cu(Ⅱ), Ni(Ⅱ) andCo(Ⅱ) has been studied. It was observed that thecatalytic activity is in the orderCu(Ⅱ)>Co(Ⅱ)>Ni(Ⅱ). The activation energies wereestimated to be approximately 41, 70 and 74KJ mol-1 inthe presence of Cu(Ⅱ),Co(Ⅱ) and Ni(Ⅱ), respectively.
