过二硫酸盐与锰(Ⅱ)盐的催化反应研究

Study on the Catalytic Reaction of S_2O_8^(2-)Salt and Mn(Ⅱ) Salt

过二硫酸盐与锰 (Ⅱ )盐所进行的氧化还原反应 ,在极少量的金属离子存在下 ,反应速率明显加快。实验表明 ,除Ag+离子外 ,Cu2 +、Zn+都具有催化作用 。

In the oxidation reduction reaction of S 2 O 2- 8 salt and Mn(Ⅱ) salt, the reaction rate was accelerated in the presence of small amount of metal ion. The experiments showed that except for Ag + , Cu 2+ and Zn 2+ have catalysis, and the reaction rate can be increased with heating.
