摘    要:用碘量法测定稳定性二氧化氯溶液中二氧化氯(ClO2)含量时,当稳定剂中过氧水合碳酸钠过量时,测定结果会偏高,如采用将待测样酸化后加入略过量的K2Cr2O7与其中的H2O2反应,从而消除其影响,再用碘量法测定,就可较准确地测定稳定性二氧化氯溶液中ClO2的真实含量。

关 键 词:二氧化氯  稳定性溶液  碘量法测定

Abstract:The content of ClO 2 in a stabilized chlorine dioxide solution, determined by iodometric method, always deviates to be higher if peroxo-hydrous sudium carbonate is excessive. However, a few excessive potassium bichromate added into the acidated specimen reacts with hydrogen peroxide and dispel the negative effect of peroxohydrous sodium carbonate. Thus the exact content of ClO 2 can be determined.
Keywords:chlorine dioxide  stabilized solution  iodometric method
