摘　　要：本文提出了利用X-荧光仪测定废塑料各种金属涂层中金属元素含量的方法。以稳定性为优化原则选择了仪器针对不同元素的测量条件,研究了实验过程中样品杯、基材以及金属涂层中元素效应对检测结果的影响;方法精密度为0.008%～0.044%之间;将X-荧光检测结果与ICP检测结果进行比对并得出同样的数据,该方法为控制废塑料金属涂层产生的危害和污染提供更为合理的检测手段,并已应用到实际检测当中。A new method for determining every metal elements in the metallic coating of waste plastics by Xray fluorescence spectrometer was bronght out. The instrument working conditions for different elements were opti-mized according to the stability,the effects of sample cup,base material and matrix elements for the determinated results were discussed; RSDs were in the range of 0.5%～1.5%,The results were given indifferent by XRFS and ICPOES were compared and gave uniformity results. This method can give more reasonable results for controlling dam-age and contamination by metallic coating of waste plastics. It also has been applied to practical sample analysis.
