稳定性二氧化氯溶液活化研究

稳定性二氧化氯溶液在使用时需加活化剂将其活化以释放活性成分二氧化氯，为此研究了活化剂种类、稳定液质量浓度、活化剂用量与质量浓度、温度等因素对活化效果的影响。结果表明：活化剂酸性强、质量浓度高、用量大则活化快；稳定液质量浓度低、操作温度高有利于活化；用柠檬酸活化时活化速度慢，活化效率较低，在15℃下以1：10的摩尔比用饱和柠檬酸溶液活化157．3mg／L的稳定液9h，活化效率仅为35％。基于此特性，可以将柠檬酸作为稳定液中二氧化氯的缓释剂。

Study on activation of stabilized chlorine dioxide solution

When stabilized chlorine dioxide solution is used, activator is added within it to release the active component ClO2. Therefore, the influence on the activation effect was studied by many factors, including several kinds of activator, different stable solution concentration, different activator dosage and concentration, and operation temperature. The result indicates that the acidic of activator is strong, the concentration of activator is high and the dosage of activator is large, and the activation is quickly. The low concentration of stabilized solution and high operating temperature make for activation. When the stabilized solution is activated by citric acid, the activation speed is slow and the activation efficiency is lower. At 15 ℃, using saturation citric acid solution, the 157.3 mg/L stabilized chlorine dioxide solution is activated for 9 h with 1 ： 10 molar ratio, the activation efficiency is only 35%. Based on this properties, citric acid can be used as slow release agent of ClO2 in stable solution.
