摘　　要：试验采用高分辨率电感耦合等离子体质谱法(High-Resolution Inductively Coupled Plasma Mass Spectrometry,HR-ICP-MS)测定钨钼矿石中钨、钼、锂、铬、钴、镍、铜、锌、镓、锗、砷、硒、铷、铌、铟、锡、锑、铼、铊和铋等元素的含量。参考国家一级标准物质,对HR-ICP-MS进行数据比较和精确度验证,按照相关标准规定的方法确定HR-ICP-MS的检出限。结果表明,采用HR-ICP-MS测量钨钼矿石金属元素的相对标准偏差(Relative Standard Deviation,RSD)为0.86%~9.70%,各元素的检出限介于0.002~27.000 mg/kg,加标试验后的回收率损失小于2%,该方法可靠可信,准确度和精密度都能达到测试要求。The experiment uses High-Resolution Inductively Coupled Plasma Mass Spectrometry(HR-ICP-MS)to determine the content of elements such as tungsten,molybdenum,lithium,chromium,cobalt,nickel,copper,zinc,gallium,germanium,arsenic,selenium,rubidium,niobium,indium,tin,antimony,rhenium,thallium,and bismuth in tungsten molybdenum ore.Referring to national first level standard substances,data comparison and accuracy verification of HRICP-MS are conducted,and the detection limit of HR-ICP-MS is determined according to the methods specified in relevant standards.The results show that the Relative Standard Deviation(RSD)of metal elements in tungsten molybdenum ore measured by HR-ICP-MS is 0.86%~9.70%,and the detection limit of each element is 0.002~27.000 mg/kg,and the recovery loss after the spiking test is less than 2%,and this method is reliable and believable,and both accuracy and precision can meet the testing requirements.
