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 anodic reaction of electrolyzed saturated potassium hydrogen sulfate and saturated potassium sulfate solution was studied by using perturbation technique. It was found that the HSO-4 ion was easily oxidized at the anode compared with SO2-4 ion. The reaction was 2HSO-4 = S2O2-8 + 2H + + 2e. The possible reaction mechanism was discussed.
