Stability of the by-product sodium hypochlorite in the chlor-alkali industry
Thread Content
At present, sodium hypochlorite is widely used for disinfecting tap water. The concentration of the ready-made sodium hypochlorite solution is around 10%, and it is a by-product of chlor-alkali production. I would like to ask: since sodium hypochlorite decomposes easily, the higher the concentration, the more likely it is to decompose. Is it necessary to add any stabilizers? ? Does anyone know? ?
Sodium silicate + sodium chloride, but the ratio is based on empirical data obtained by manufacturers of sodium hypochlorite stabilizers; however, in my opinion, the main reaction itself produces sodium chloride as a by-product, and adding sodium silicate in the appropriate proportion is sufficient to meet the requirements.
