高稳定性次氯酸钠消毒剂的研制

DEVELOPMENT OF HIGHLY STABLE SODIUM HYPOCHLORITE DISINFECTANT

为研究高稳定性次氯酸钠溶液,采用加入稳定剂的配制工艺制成次氯酸钠溶液并对其有效氯稳定性进行了观察。结果,在含有效氯17.5、35、70、140 g/L的次氯酸钠溶液内依次加入3、11、20、40的A-1b型稳定剂配制而成的高稳定性次氯酸钠消毒剂在54℃条件下储存14 d,有效氯下降率均小于10%。未加入稳定剂的相同浓度次氯酸钠溶液,54℃贮存14 d,有效氯下降率均大于29.48%以上。结论,该高稳定性次氯酸钠消毒剂在54℃条件下储存14 d,其有效氯下降率在规定的有效范围。

In order to study the highly stable sodium hypochlorite solution, sodium hypochlorite solution was prepared using reconstituting technology by adding stabilizer and its available chlorine stability was observed. Results： The available chlorine contents of the highly stable sodium hypochlorite disinfectants prepared by adding type A _ Ib stabilizer 3, 11, 20 and 40 g/L to the sodium hypochlorite solutions containing available chlorine 17.5, 35, 70 and 140 g/L respectively decreased by less than 10% after storing at 54℃ for 14 days. The available chlorine contents of the sodium hypochlorite solutions without stabilizer at the same concentrations decreased by over 29.49% after storing at 54℃ for 14 d. Conclusion： The rate of decrease in available chlorine content of the highly stable sodium hypochlorite disinfectant after storing at 54℃ for 14 d is within the specified effective range.
