| 摘 要： | 建立了一种测定水中的ClO2、Cl2、ClO2^-、ClO3^-离子色谱法，在含有碳酸氢钠缓冲溶液的中性条件下，用NaNO2将ClO2、Cl2还原为ClO2^-、Cl^-，通过测定ClO^-和NO3^-的变化值，间接测定ClO2和Cl2。加入硫代乙酰胺(TAA)作掩蔽剂测定ClO2^-。

| Abstract: | An ion chromatographic (IC) method has been developed for the determination of chlorine dioxide, chlorine, chlorite and chlorate in water. In neutral medium containing NaHCO 3 buffer, chlorine dioxide and chlorine were reduced to chlorite and chloride by adding sodium nitrite. Chlorine dioxide and chlorine were determined indirectly by the measurement of varied chlorite and nitrate with IC method. Thiacetamide was used as a masking agent for chlorite. |
