摘　　要：对火焰原子吸收法测定铅阳极泥金属化物料中的碲的测定条件进行了探索。对物料中各干扰元素进行了回收试验,碲回收率为99. 40%～102. 10%;同时进行了精密度试验,RSD为0. 48%～0. 96%;对3种物料样品阳极泥1#、合金2#、渣3#进行了加标回收试验,碲回收率为99. 14%～100. 80%,满足火法还原试验生产需要。The determination conditions of tellurium in metalized material of Lead Anode Slime by flame atomic absorption spectroscopy method is studied. The recovery test is carried out for each interference element in the material,the recovery rate of tellurium is99 40% - 102 10%;The precision degree test is carried out simultaneously,RSD is 0 48% - 0 96%;the adding standard recovery test iscarried out for three kinds of material samples that anode slime 1#,alloy 2#,slag 3#,the recovery rate of tellurium is 99 14% - 100 80%,which can meet the requirements of pyrogenic reduction test and production.
