摘要
本文介绍了ＩＣＰ－ＭＳ测定河底积物中１５种稀土元素和钍的方法．工作中就仪器的工作参数对被测元素的影响和常用的硝酸、盐酸以及高纯去离子水中杂质和工作气体产生的干扰进行了研究；讨论了ＩＣＰ－ＭＳ和ＩＣＰ－ＡＥＳ检测限的差异并与文献值比较。测量了标准物质和河底沉积物样品，所得结果与推荐值吻合较好。
A method of determination of REE and Th in sediment by ICP-MS has been developed. The influences of instrumental parameters and HNO_3,HCI and argon gas on REEand Th were studied. The difference of DL between ICP-MS and ICP-AES was discussed,and compared them with those in literature. The results of REE and Th in SDM-2/TM measured are good agree with the recommend values.
