摘要：
提出利用便携式X-荧光仪与ICP-AES联同检测废塑料金属涂层中5种金属元素含量的方法。以稳定性为优化原则选择仪器的工作条件,研究共存元素的影响和酸度效应,铝、铜、锌、镍、铬等金属元素检出限为0.006%~0.009%,相对标准偏差为0.5%~1.5%,回收率为90%~106%。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,已应用于实际检测工作当中。

Abstract: A new method for determining five metal elements in the metallic coating of waste plastics by portable X-ray fluorescence spectrometer and ICP-AES was proposed in this paper. The instrument working conditions were optimized according to the stability. And acidity effect and matrix effect were discussed. The detection limits of aluminum, copper, zinc, nickel and chromium were in the range of 0.006%-0.009%, RSDs were in the range of 0.5%-1.5%, and recoveries were 90%-106%. This method can give more reasonable results for controlling damage and contamination by metallic coating of waste plastics. It also has been applied to practical sample analysis.
