摘　　要：提出简便、快速、灵敏的AAS法测定铊。采用聚氨脂泡沫(PF)塑料吸附富集铊,大量的金属离子和阴离子完全不干扰。此法用于测定矿石、钼精矿和铜精矿中微量铊,获得了满意的结果。A simple,rapid and sensitive method for the determination of thallium with AAS is presented. The seperation and enrichment of thallum are done by adopting polyurethane foam （PF）. A large number of metal ions and commonanions do not interfere. The method has been used for the determination of trace Tl in ores, molybdenum ores, copper concentrate. Satisfactory results are obtained.
