摘要
二氧化氯(ClO_2)是一种高效饮用水消毒剂。不仅能杀灭水中微生物,氧化溶于水中的铁和锰盐使之沉淀,还可减少水中的致癌物质。由于它属易燃易爆气体,不利贮运,水溶液也不稳定,给应用带来不便。美国International
The solution of stabilized chlorine dioxide can release chlorine dioxide quickly by addition of acidic activator. The chlorine dioxide has quick germicidal action. It was indicated in laboratory experiment that a three-minute exposure to a solution containing 2.0 mg/L of chlorine dioxide could kill 99.9999% Escherichia coli in water and one-minute exposure could completely inactivate coli phage f_2 in water. A solution containing 250 mg/L of chlorine dioxide could inactivate HBsAg in serum after contact for 5 min. The disinfectant can be used for disinfection of drinking water.
