摘要
采用离子色谱仪检测工业甲醇中微量氯离子的方法,需首先对甲醇样品进行浓缩处理,使用阴离子柱为分析柱,热导检测器,分析检测的RSD为5.9%,回收率为92.0%～100%,检测限为0.02 mg/L,可以满足工业甲醇中微量甲醇氯离子含量的检测需要.
Abstract
This article uses an ion chromatograph to detect trace chloride ions in industrial methanol.Firstly,the methanol sample is concentrated and treated using an anion column as the analysis column and a thermal conductivity detector.The RSD for analysis and detection is 5.9%,the recovery rate is 92.0%～100%,and the detection limit is 0.02 mg/L.This can meet the needs of detecting trace chloride ions in industrial methanol.
