测定饮用水中亚氯酸盐和氯酸盐影响因素的研究

Study on influence factors of chlorite and chlorate in drinking water

二氧化氯作为一种新型消毒剂,由于消毒效果较好,安全性较高的特点,近年来被广泛应用于饮用水消毒,但其消毒后产生的无机消毒副产物也不容忽视,本文主要运用离子色谱对亚氯酸盐和氯酸盐测定的影响因素进行了分析,其中包括取样通氮气、加固定剂、静态及动态下接触时间、输水距离及试验环境对亚氯酸盐和氯酸盐的生成变化规律,以提高检测数据的准确性和可靠性,为饮用水安全保障提供试验依据。

As a new type of disinfectant,chlorine dioxide has been widely used in drinking water disinfection in recent years because of its good disinfection effect and high safety.However,the inorganic disinfection byproducts produced after disin fection can not be ignored.In this paper,the influencial factors of chlorite and chlorite determination are analyzed by ion chromatography,which includes sampling nitrogen,fixing agent,static and dynamic contact time,water distance and the change of chlorite and chlorate formation in the test environment-In order to improve the accuracy and reliability of the test data for and to provide experimental basis for drinking water safety.
