摘要
采用有机-碱液消解法对电子电气产品PVC部件进行前处理,再用分光光度法测出六价铬[Cr(Ⅵ)]。优化试验操作流程和仪器工作条件,测定结果准确度与精密度均符合实验要求,并着重指出在实验中需要注意的一些情况。
The PVC components of electronic and electrical products were pretreated by organic alkali digestion method, and hexavalent chromium [Cr(Ⅵ)] was determined by spectrophotometry. The operation process of the test and the working conditions of the instrument were optimized, and the accuracy and precision of the measurement results met the requirements of the experiment.
