电解金属锰样品用HNO3+HC1经微波消解后,直接用电感耦合等离子体质谱法(ICP-MS)同时测定了试液中Na、Mg、Ti、V、Co、Ni、Cu、Zn、As、Mo、Cd、Sb、Pb等13种痕量元素.通过优化仪器工作参数、选择适宜待测元素的同位素以及选用干扰元素校正方程克服了质谱干扰,使用内标元素消除了基体干扰.结果表明,Mg、V、Co、Ni、Cu、Zn、As、Mo、Cd、Sb、Pb等11种痕量元素的检出限在0.001～0.086 μg/L之间,Na和Ti元素的检出限在0.16～0.19μg/L之间.将本方法用于测定电解锰样品,加标回收率在95％～106％之间,相对标准偏差(RSD)小于3.5％.方法与其它分析方法对照,结果一致.
