Scope
Scope: This document specifies the requirements, test methods, inspection rules, marking and accompanying documents, as well as packaging, transportation, and storage for low-chlorine potassium persulfate. This document applies to low-chlorine potassium persulfate produced using ion-exchange membrane potassium hydroxide as the raw material. Note: This product is mainly used as an initiator for polymers of three synthetic materials (synthetic rubber, synthetic resin, and synthetic fiber), an additive for petroleum cracking, an oxidizing agent, a disinfectant, and an initiator for emulsion polymerization; Main technical content: Item Technical Requirements Potassium persulfate (K2S2O8) w/% ≥99.0 Active oxygen (O) w/% ≥5.86 pH (50 g/L solution) 4.0–7.0 Iron (Fe) w/% ≤0.0005 Chloride (calculated as Cl) w/% ≤0.005 Moisture w/% ≤0.05 Manganese (Mn) w/% ≤0.0001 Heavy metals (calculated as Pb) w/% ≤0.001 Ammonium salt (calculated as NH4) w/% ≤0.20
