| 摘 要： | 研究了次氯酸钠水溶液的稳定性，考察了温度、pH值、金属离子种类和浓度、表面活性剂等对次氯酸钠溶液稳定性的影响。结果表明，在温度低于25℃、pH大于12．6时，次氯酸钠溶液稳定性较好，溶液中Ca^2 、Mg^2 离子的存在对次氯酸钠溶液稳定性影响不大；而Fe^2 、Mn^2 离子的存在会促进其分解；表面活性剂硅酸钠可作为次氯酸钠消毒液的良好添加剂。

| Abstract: | The stability of aqueous sodium hypochlorite solution was studied. The effect of temperature, pH, type and concentration of metal ions and surfactants on the stability of sodium hypochlorite solution were investigated. The results showed that the solution was fairly stable at temperature <25 and pH>12.6. The effect of Ca~(2+) and Mg~(2+) on stability of aqueous sodium hypochlorite could be neglected, but the Mn~(2+) and Fe~(2+) could dramatically increase the decomposition rate. The aqueous sodium hypochlorite solution had great stability when surfactant, sodium silicate, was added. |
