T/LNWTA 009-2021 Standard for chromium ion content in brine for water treatment agent and diaphragm electrolysis to prepare sodium hypochlorite and chlor alkali (English Version)
This standard specifies the chromium ion content standards in water treatment agent sodium hypochlorite and chlor-alkali raw material sodium chloride solution, mainly including measurement methods and content standards. This standard is applicable to the detection of chromium in electrolytic sodium chloride solution. This standard is mainly used for the determination of sodium chloride solutions in the process of preparing sodium hypochlorite and chlor-alkali from drinking water and industrial water.
