摘　　要：为了解稳定性二氧化氯常用活化剂的活化性能 ,对一些固体和液体活化剂进行了比较研究。结果 ,以pH值≤ 2 .0时最高活化率为参考标准 ,当液体亚氯酸钠与盐酸比例为 5∶4时 ,pH≤ 2 .0 ,二氧化氯活化率达到 80 %以上 ;当固体亚氯酸钠与柠檬酸或草酸比例为 1∶4时 ,pH值≤ 2 .0 ,二氧化氯活化率分别接近 6 0 %和 80 %。结论 ,稳定性二氧化氯活化剂以盐酸活化效率最高 ,用固体有机酸作为活化剂 ,其二氧化氯活化率只能达到 80 %左右。In order to know the activation properties of the common activators of stable chlorine dioxide, comparative study on some solid and liquid activators was carried out. Results: With the highest activation rate at pH ≤2.0 as the reference standard, when the ratio of liquid sodium chlorite to hydrochloric acid was 5∶4, the pH value was ≤2.0 and the activation rate of chlorine dioxide attained over 80%. When the ratio of solid sodium chlorite to citric acid or oxalic acid was 1∶4, the pH value was ≤2.0 and the activation rate of chlorine dioxide approximated 60% and 80% respectively. Conclusion: Among the activators of stable chlorine dioxide, hydrochloric acid had the highest activation rate. When solid organic acid was used as the activator, the activation rate of chlorine dioxide could only attain about 80%.
