摘　　要：探索用硝酸对硫酸铝样品进行预处理,以ICP-OES同时测定锑和硒含量的方法。本方法测定锑和硒的加标回收率在86.2%~99.3%之间,相对标准偏差均小于1.68%,线性范围均为0.9999,检出限分别为0.07μg/g和0.19μg/g。本方法预处理简单快捷,检出限低,准确性良好,适用于水处理剂硫酸铝中锑和硒的同时测定。A method of simultaneous determination of antimony and selenium in aluminum sulfate by Inductively Coupled Plasma Optical Emission Spectroscopy-HNO_(3) digestion is described.Recovery of this method ranges from 86.2%~99.3%,all relative standard deviations is less than 1.68%and both calibration curves yield 0.9999 correlation coefficient.The limits of detection for antimony and selenium are respectively 0.07μg/g and 0.19μg/g.This method achieves simple digestion process,low limit of detection and high accuracy and is applicable to simultaneous determination of antimony and selenium in aluminum sulfate.
