Scope
Scope: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage for sodium sulfate, a by-product of organic peroxides (hereinafter referred to as "sodium sulfate"). This document applies to the quality control of sodium sulfate obtained by purifying and evaporating the mother liquor produced from organic peroxides using sulfuric acid, hydrogen peroxide, tertiary alcohols, and sodium hydroxide as the main raw materials. Sodium sulfate is mainly used in industries such as textile dyeing, glass, and papermaking. Main technical contents: - Requirements: - Sodium sulfate content, w/w% ≥ 99.0 - Water-insoluble matter, w/w% ≤ 0.05 - Calcium and magnesium ions (calculated as Mg), w/w% ≤ 0.1 - Chloride ions (calculated as Cl), w/w% ≤ 0.1 - Iron (Fe) / (mg/kg) ≤ 20 - Moisture, w/w% ≤ 0.2 - Whiteness (R457), % ≥ 82 - Total organic carbon (calculated as C) / (mg/kg) ≤ 1,500
