摘要
建立了微波消化、等离子体质谱同时测定人发样品中２０种元素含量的方法，对影响测定结果的因素进行了讨论和优化，所测元素的检出限（３σ，ｎ＝１１）最高为１．３９ｎｇ／ｍＬ（Ｓｅ），最低为０．０００１ｎｇ／ｍＬ（Ｂａ），标准加入回收率介于９５％～１１０％之间，对国家标准物质样品分析的结果与所给参考值一致．本方法具有灵敏度高，基体干扰小，简便快速，结果可靠等优点，已成功地应用人发样品中微量元素的测定．
Contents of twenty elements in human hair were measured with microwave digestion and inductively coupled plasma massspectrometry (ICPMS). The experimental conditions were discussed and optimized. Detection limits(3σ,n=11) results indicated that the highest DL was 1.39 ng/mL(Se) and the lowest was 0.000 1 ng/mL (Ba). The recoveries of spikes for 20 elements were between 94%~110%. The analytical results of national certified reference material demonstrated the applicabilityof the proposed method.
