摘　　要：建立一种离子色谱法测定电子级试剂-四甲基碳酸氢铵中痕量的HCOO^(-)、Cl^(-)、NO_(3)^(-)的定量分析方法。使用IonPac AS11-HC型分析柱和IonPac AG11-HC型保护柱,KOH淋洗液进行梯度淋洗,流速为1.0mL/min,进样体积为100μL。在优化条件下,各离子的最低检出限为0.021~0.050mg/L,保留时间、峰面积于峰高的相对标准偏差均小于2.415%,各离子相关系数均大于0.9990。该方法前处理操作简单、准确,并且有较好的重现性和较低的检出限,可应用于四甲基碳酸氢铵中的3种痕量阴离子的同时测定。Ion chromatographic method was established for the determination of trace HCOO^(-),Cl^(-) and NO_(3)^(-)in the electronic grade reagent-tetramethylammonium bicarbonate.The ion chromatography was performed on an IonPac AS11-HC analytical column and an IonPac AG11-HC guard column with a gradient elution of KOH eluent at a flow rate of 1.0 mL/min and an injection volume of 100μL.The limits of detection for each ion were 0.021~0.050 mg/L under the optimized conditions,and the relative standard deviations of retention time,peak area and peak height were less than 2.415%,and the correlation coefficients of each ion were greater than 0.9990.The method is simple and accurate,and has good reproducibility and low detection limits,and can be applied to the simultaneous determination of three trace anions in tetramethylammonium bicarbonate.
