摘　　要：便携式X射线荧光光谱仪(p-XRF)因具有快速、廉价和无损检测元素含量的能力,通常被用于野外或实验室地质样品元素含量快速检测工作中,并取得了良好的效果;但p-XRF能否用于尾砂样品测试,相关研究则尚未系统开展。为了查明p-XRF分析尾砂样品的可靠性,本文对比了p-XRF与实验室分析测试数据,结果表明:(1)p-XRF可用于尾砂样品的Cu、S、Fe等主要元素的定量分析;(2)p-XRF对于尾砂中Se、Ti、Sr、Zn、Mn、As、Rb、Mo等微量元素的测试结果具有较高的准确度;(3)p-XRF对于尾砂中Co、Cr、V、Nb、Ag等微量元素的测试结果误差较大,只能给出定性的分析结果。Portable X-ray fluorescence spectrometer(p-XRF)is usually applied to rapid determination of element content in a geological sample in the field or laboratory because it is rapid,cheap and nondestructive.However,whether p-XRF can be used to test tailings samples has not been systematically studied.In order to find out the reliability of p-XRF analysis of tailings samples,this paper compared p-XRF and laboratory test data,giving the following results:(1)p-XRF can be used for quantitative analysis of Cu,S,Fe and other major elements in tailings samples;(2)p-XRF has high accuracy in determinations of trace elements such as Se,Ti,Sr,Zn,Mn,As,Rb and Mo in tailings;(3)p-XRF has a large error in determinations of trace elements such as Co,Cr,V,Nb and Ag in tailings,thus only providing qualitative analysis results.
