次氯酸钠水溶液的稳定性研究

Study on Stabilization of Sodium Hypochlorite Aqueous Solution

次氯酸钠在医院、饮食业及工业循环水等方面有广泛的应用,但次氯酸钠溶液在常温下很快会发生分解,造成性能下降。对次氯酸钠水溶液的稳定性进行了试验,结果表明:在次氯酸钠水溶液中加入复合稳定剂0.005%EDTA、1%硅酸钠、0.1%碳酸氢钠和0.2%氯化钠,可使次氯酸钠溶液的稳定性提高10%。

Sodium hypochlorite is used extensively in many fields,such as hospitals,eating and drinking service and industrial circulating water.However,sodium hypochlorite will decompose quickly at normal temperature,which reduces its function.This essay does some study on the stabilization of sodium hypochlorite aqueous solution.It shows that the stabilization of sodium hypochlorite can increase by 10% if we add a composite stabilizer containing 0.005%EDTA,1%sodium silicate,0.1%sodium bicarbonate and 0.2% sodium chloride.
