Use

It can be derived by the electrolysis of ammonium sulfate and dilute sulfuric acid and then crystallized. Electrolytic process Ammonium sulfate and sulfuric acid formulates to form liquid electrolyte, it is decontaminated by electrolysis, HSO4-can discharge and generate peroxydisulfate acidat in the anode, and then reacts with ammonium sulfate to generate ammonium persulfate, ammonium persulfate goes through filtration, crystallization, centrifugal separation, drying to get ammonium persulfate product when the content reaches a certain concentration in the anode. Anode reaction: 2HSO4--2e → H2S2O8 Cathodic reaction: 2H ++ 2e → H2 ↑ (NH4) 2S2O4 + H2S2O8 → (NH4) 2S2O8 + H2SO4
