摘　　要：建立了一种选用高效阳离子交换色谱,抑制型电导检测的方法,分析印刷线路板提取液,即75%异丙醇中常见碱金属和碱土金属的方法。选择的色谱条件是高容量阳离子交换柱IonPacCS12A,手工配置18mmol/L甲烷磺酸,配有连续自动再生微膜抑制器的数字电导检测器进行检测。该方法具有结果准确、方法快速、操作简单、选择性好的特点。方法检出限均低于10μg/L,线性范围均超过两个数量级,线性系数r均可达到0.9998以上。标准加入回收率范围为91%～104%,连续进样重现性RSD<2.40%。The present paper established a new method for analyzing cations in 75% IPA which was used to extract anions and cations from the surface of PCB by ion chromatography method.The chromatographic equipment consisted of an IonPac CS12A cation exchange column and 18 mmol/L of MSA isocratic eluent coupled with a suppressed conductivity digital detection meter that could achieve good reproducibility,selectivity,sensitivity and veracious results.Also this method could give good linear range and spiked recoveries as well.
