摘　　要：建立了离子色谱柱后衍生法测定电器电子产品中六价铬的方法。方法研究了样品前处理条件和离子色谱条件,并与紫外可见分光光度法进行比较,六价铬的检出限为0.5μg/L,加标回收率为95.3%~102.0%,相对标准偏差为3.20%~4.32%。该方法操作简单快速、准确度高,适合电器电子产品中六价铬的测定。The sample pretreatment and ion chromatography conditions were studied, and this method was compared with the method of UV-Vis spectrophotometry. The detection limit of hexavalent chromium was 0.5 mg/kg, and the recoveries were in the range of 95.3%-102.0% while the relative standard deviation results were within 3.20%-4.32%. This method is simple, fast, accurate and suitable for the de termination of hexavalent chromium in electrical and electronic products.
