基于碰撞理论的次氯酸钠水溶液稳定性的研究

以碰撞理论为模型，对次氯酸钠溶液的分解机理进行了研究，得出次氯酸钠溶液在无催化剂影响条件下的主要分解方程式。研究表明，在强碱性条件下次氯酸钠的分解主要是通过CIO水解生成HCIO引发的一系列反应；歧化反应是通过HCIO的分解生成的[O]实现的；在强碱条件下，次氯酸钠的分解速率与溶液的初始浓度有关，而反应前后溶液pH值、游离碱含量却几乎不发生变化；升高温度会增加有效碰撞，从而提高反应速率。次氯酸钠溶液添加0．2％、0．6或1．O％的硅酸钠后，体系稳定度变化不大。

Study on stability of aqueous sodium hypochlorite solution based on the theory of collision

The mechanism of sodium hypochlorite solution's decomposition was studied based on the theory of collision model.The main reaction equations of sodium hypochlorite solution's decomposition were obtained without catalysts.Research shows that the decomposition of sodium hypochlorite are cascade of reactions that mainly triggered by the hydrolysis of ClO-which to form HClO in a strong alkaline condition.Disproportionation of sodium hypochlorite is generated by the [O] which formed from hypochlorous's decomposi...
