含氯消毒剂加防锈剂的浓度研究

目的 探讨含氯消毒剂加防锈剂亚硝酸钠的最佳浓度。方法 以“九星牌84消毒液”为代表，将30份消毒液样品按盲法设计，并随机分成不同亚硝酸钠浓度的5个实验组和1个空白消毒液对照组，观察各组有效氯浓度变化情况和防锈作用。结果 加入亚硝酸钠浓度不同，消毒液的有效氯浓度变化情况和防锈作用不同。结论 含氯消毒剂加亚硝酸钠作为防锈剂是可行的；加入亚硝酸钠的最佳浓度为0.01%，其次为0.05%。

The Optimal Concentration of Sodium Nitrite in Chlorine Disinfectants

Objective To study the optimal concentration of sodium nitrite in chlorine disinfectants.Methods Thirty samples of Jiuxing 84 disinfectant were numbered according to the blind method design,and randomly divided into five groups based on different concentrations of sodium nitirte and one blank sample group was used as control.Results The different concentrations of sodium nitrite had different effects on the concentration of the disinfectant and rust proof action.Conclusion It was practicable to use sodium nitrite in the disinfectant as a rust proof agent.The optimal concentration of sodium nitrite was 0.01% and 0.05%.
