| 摘 要： | 实验研究了温度、有效氯含量、含盐量等因素对次氯酸钠溶液氧化性的影响。结果发现:常温常压下,漂水氧化还原电位主要受pH值控制,随着pH值的降低而升高;在pH值不变的情况下,漂水氧化还原电位与有效氯含量呈二次函数关系;漂水的稳定性与温度、pH值有很大的关系,在高温或低pH值的情况下极易分解,提高含盐量对提高其稳定性有一定帮助。

| Abstract: | The influences of such factors as temperature,active chlorine content,salt content on the(oxidizing) property of sodium hypochlorite solution are studied by experiments.The following results are found.The oxidation reduction potential of sodium hypochlorite solution is mainly controlled by pH value under room temperature and normal pressure and increases with the reduction of pH value.The relation between oxidation reduction potential of sodium hypochlorite solution and active chlorine content appears a quadratic function with unchanged pH value.The stability of sodium hypochlorite solution is greatly(depended) on temperature and pH value.Sodium hypochlorite tends to decompose very easily at the condition of high temperature or low pH value.The increase of salt content helps to improve its stability. |
