【Abstract】 This paper suggested using Mn 2+ and Ni 2+ as catalyst for the oxidation of sodium polysulfite to produce sodium thiosulfate. This method obviously accelerated the speed of oxidation and needed no heating in the process of oxidation. It can be completely oxidized at indoor temperature. Compared with the traditional technology, this method had the following advantages: no pollution, higher speed, lower energy consumption, stable quality and easy operation.更多还原
