Introduction

At present, domestic industrial persulfate products are mainly divided into three types. industrial sodium persulfate, industrial potassium persulfate, and industrial ammonium persulfate. To improve The integrity of the standard system for industrial persulfate products is to integrate the standards to facilitate the implementation of this standard by relevant units. GB/T 26519 "Industrial Persulfate" is intended to be composed of three parts. ---Part 1.Industrial sodium persulfate; ---Part 2.Industrial potassium persulfate; ---Part 3.Industrial ammonium persulfate. Industrial persulfate Part 3.Industrial Ammonium Persulfate Warning. According to the provisions of Chapter 6 of GB 12268-2012, this product belongs to the 5th item 5.1 oxidizing substance. Part of the reagents used are corrosive. Care should be taken when handling. If splashed on the skin or eyes, rinse immediately with water. medical.
