摘要
采用X射线荧光光谱法测定废塑料表面涂层中8种元素的含量。考察了样品杯、基材以及金属涂层中元素效应对检测结果的影响。P、Si、Fe、Pb、A1、Cu、Cr和Ni的测定范围在0．002％～52．0％之间，检出限在0．0002％～O．0008％之间。采用本方法测定废塑料样品表面涂层中元素含量，结果与ICP—AES测定结果一致，测定值的相对标准偏差（n=7）小于1％。
X-ray fluorescence spectrometry was applied to the determination of 8 elements in the coating of waste plastics. The effects of the sample cup and the elements in the matrixes and the coating on the determination results were discussed. The determination ranges of P, Si, Fe, Pb, A1, Cu, Cr and Ni were between 0. 002%- 52.0%, and the detection limits were in the range of 0. 000 2%-0. 000 8%. The proposed method was used to determine 8 elements in the coating of waste plastic samples, giving results in agreement with those obtained by ICPAES, with RSDs （n=7） less than 1%.
