摘　　要： 本文讨论了用衬钽石墨管测定人体脏器中钼的方法。衬钽管完全消除了形成稳定碳化物的影响，灵敏度较用普通石墨炉管提高约８４倍，较用热解石墨管提高了一个数量级，完全消除了记忆效应，减少了钠、钾、铁等共存元素的干扰。方法简单、准确、快速。 A new method for the determination of Mo in the heart by tantalum lining graphite tube was developed.The tantalum lining graphite tube can entirely eliminate effects of stable carbide formed.The sensitivity was enhanced to compare with the conventional graphite tube.At the same time,it also eliminates memory effect completely and reduces the interferences of coexistent elements such as Fe,Na,K etc.The method is simple,accurate and rapid.
