摘　　要： 本文建立了用衬钽石墨管测定全血中钡的方法．衬钽管完全消除了形成稳定碳化物的影响和记忆效应，灵敏度较普通石墨炉提高了约３０倍，并大大减少了钾、钠、钙、镁等共存元素的干扰，节省用样量，特别适用于人血样品的分析． A method for the determination of Ba in the blood by lining tantalum graphite tube is developed The tube can wholly eliminate effects forming stable carbide of Ba The sensibility is much higher than that of the general graphite tube At the same time,it also eliminates memory effect completely and reduces the interferences of coexist elements such as Ca,Mg,Na,K,Fe The result is satisfactory
