摘　　要：氧化还原是湿法冶金中的重要过程,高氧化电位的氧化剂可以有效强化这一过程。过一硫酸(H2SO5)具有较高的氧化电位,研究了以电化学方法制备过一硫酸,考察了电解电压、电解温度、隔膜材料以及添加剂等因素对制备的影响。电解制备过程中,过一硫酸的生成与氧气的生成相互竞争,适当提高电解电压并加入添加剂,可有效抑制析氧副反应的发生。通过单因素试验,得到了较优的工艺条件,为后续研究和工业应用奠定了相关基础。The oxidation-reduction is an important process in hydrometallurgy and the oxidant with high oxidation potential is an effective means to reinforce the process.Preparation of caro＇s acid by electrolysis is reseached.The electrolysis voltage,electrolysis temperature,membrane materials,additives and other important factors are examined.The results show that the formation reactions of caro＇s acid and oxygen are competitive over the course of electrolytic preparation,appropriately increasing the electrolysis voltage and electrolytic additives can inhibit by-reaction of oxygen evolution and enhance the synthesis efficiency.Through single factor experiments,the optimum conditions were found and lay the foundation for further research and industrial applications.
