| 摘 要： | 本文采用单柱离子色谱系统测定了Ｃ２Ｏ＾２－４，以１．３ｍｍｏｌ／Ｌ葡萄糖酸钠／１．３ｍｍｏｌ／Ｌ硼砂为淋洗液测定Ｃ２Ｏ＾２－４，８常见阴离子Ｃｌ＾－，ＮＯ＾－３，ＨＰＯ＾２－４，ＳＯ＾２－４不干扰测定，Ｃ２Ｏ＾２－４的检出限为０．５７ｍｇ／Ｌ，相对标准偏差为１．０７％，工作曲线的线性范围为０．５７－５００ｍｇ／Ｌ，应用本方法测定了加Ｃ２Ｏ＾２－４的自来水样，Ｃ２Ｏ＾２－４的回收率为９９．５２％。

| Abstract: | In this paper,analysis of trace oxalate by single column ion chromatography isdescribed. 1.3 mmol/L sodium gluconate and 1. 3 mmol/L borax were used as the eluent,IC-PAN anion column for the separation and conductivity detector for the detection. Thedetection limit was 0.57mg/L.The relative standard deviation was 1.07%.The calibrationplot was linear in the range of 0.57-500mg/L.his method has been applied to analyzedrinking water spiked with C2O2-4 with 99.52% average recovery. |
