摘要：
Reduction of permanganate ion (MnO4-) by hydrogen cyanide (HCN) in aqueous solution was remarkably enhanced under the freezing process, in which permanganate ion was reduced to manganese dioxide (MnO2). As compared with the several freezing speed, the rate of the redox reaction was enhanced with increasing the freezing speed. The redox reaction was found to be strongly dependent on the solution pH and the concentration of cyanide ion added.
