摘要
二氧化氯作为一种广谱、高效消毒剂已得到广泛应用。但是,其自身活泼的性质难以制备成稳定制剂,对应用推广造成了限制。综述了二氧化氯稳定相关的基本化学性质以及pH、光、温度及其他共存物质的影响。指出二氧化氯无法在水中稳定存在,只能通过调整环境条件减缓分解、歧化过程,也可以利用平衡原理保持浓度稳定。此为高纯即用稳定二氧化氯的产品开发提供理论依据。在此基础上,应进一步进行二氧化氯转化的动力学研究,或尝试络合等方法提高二氧化氯相关产品的稳定性。
Chlorine dioxide has been widely used as a kind of high effective broad-spectrum and disinfectant.However,it is difficult to be prepared to stable formulations because of its active properties,which limits its application and promotion.The chemical properties and effects of pH,light,temperature and chlorinated substance to the stability of chlorine dioxide were reviewed.It is pointed out that ClO_(2)cannot exist stably in water.It can only slow down the decomposition and disproportionation process by adjusting the environmental conditions or use the principle of equilibrium to keep the concentration stable,which provides a theoretical basis for the development of high purity and ready-to-use stable ClO2 products.On this basis,the kinetics of ClO_(2)conversion should be further studied,and methods such as complexation should be tried to improve the stability of ClO_(2)related products.
