摘要
采用离子色谱双柱串联法分离硝酸样品，以离子色谱电导检测法测定硝酸滤液中的痕量氯离子。氯离子浓度在0．01-0．30mg／L范围内与色谱峰面积成线性关系，对硝酸样品进行测定，氯离子的加标回收率为96．5％-99．0％．测定结果的相对标准偏差为1．84％-2．83％（n=5）。
The sample of nitric acid was analyzed by ion chromatography with two columns linked. A conductivity ion chromatography method was used to determine trace chloride. The concentration of chloride was linear with peak area in 0.01-0.30 mg/ L. The recoveries were 96.5%-99.0%, and the relative standard deviation was 1.84% -2.83% （n=5）.
