方法一
Method 1
硫酸钾法用硫酸铵和硫酸配制成电解液除杂质后进行电解。HSO4在阳极放电而生成过二硫酸,再与硫酸铵反应生成过硫酸铵,然后加入硫酸钾进行复分解反应,经冷却、分离、结晶、干燥,制得过硫酸钾成品。其
The potassium sulfate method uses ammonium sulfate and sulfuric acid to prepare an electrolyte for electrolysis after removing impurities. HSO4 is discharged at the anode to produce persulfate, and then reacts with ammonium sulfate to produce ammonium persulfate, then potassium sulfate is added for double decomposition reaction, and the finished product of potassium persulfate is prepared through cooling, separation, crystallization and drying. his
阳极反应:2HSO4-2e→H2S2O8
Anode reaction: 2hso4-2e → h2s2o8
阴极反应:2H+2e→H2↑
Cathode reaction: 2h + 2e → H2 ↑
(NH4)2SO4+H2S2O8→(NH4)2S2O8+H2SO4
(NH4)2SO4+H2S2O8→(NH4)2S2O8+H2SO4
(NH4)2S2O8+K2SO4+H2SO4→K2S2O8+2NH4HSO4
(NH4)2S2O8+K2SO4+H2SO4→K2S2O8+2NH4HSO4
方法二
Method 2
由过硫酸铵与硫酸钾进行复分解反应后,冷却、分离、结晶、干燥而得。
It is obtained by double decomposition reaction of ammonium persulfate and potassium sulfate, cooling, separation, crystallization and drying.
过硫酸钾用途
Application of potassium persulfate
