Abstract
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 microwave digestion and inductively coupled plasma massspectrometry (ICPMS).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.
