固相萃取-气相色谱法测定地表水中四氯化碳

摘要

In this paper, a method for the determination of carbon tetrachloride in surface water by using solid phase extraction-gas chromatography was established by optimizing solid phase extraction column, eluting solvent and sodium chloride addition.The method was simple to operate, high enrichment efficiency, less use of organic reagents, low detection limit, fine density and standard recovery rate to meet the requirements of analysis and testing. This method could meet the requirements of the determination of trace carbon tetrachloride in surface water.%文中通过优化固相萃取柱、洗脱溶剂和氯化钠加入量等化固相萃取条件, 建立了固相萃取-气相色谱法测定地表水中四氯化碳的方法.该方法操作简便, 富集效率高, 有机试剂用量少, 检出限低, 精密度和加标回收率符合分析测试要求.该法能满足地表水中痕量四氯化碳的测定要求.
