电解合成K_2S_2O_8阳极反应的研究

Anode Reaction Study on Electrolytic Synthesis of Potassium Persulfate

运用微扰技术研究了电解饱和硫酸氢钾和饱和硫酸钾溶液的阳极反应，表明ＨＳＯ－４离子与ＳＯ２－４离子相比，易于在阳极被氧化，电极反应为２ＨＳＯ－４＝Ｓ２Ｏ２－８＋２Ｈ＋＋２ｅ．探讨了可能的反应机理．

The anode reactions on electrolytic synthesis of potassium persulfate were studied by the perturbation technique for electrolyzer of saturated KHSO4 and saturated K2SO4 solution, respectively. These researches have shown that the HSO4 ion was oxidized to form S2O2-8 ion on the ahode more easily than SO2-4. THis anode reaction is 2HSO-4 = S2O2-8 + 2H+ + 2e. A possible reaction mechanism was discussed.
