摘　　要：本文采用双缝式原子捕获石英管在火焰原子吸收分光光度计上测定火药烟晕中微量铅和锑，研究了捕获的时间及乙炔的流量等测试条件。实验表明：本法提高了原子吸收分光光度法的灵敏度，铅提高４倍，锑提高了９倍。方法的回收率铅为９８．６～１０４％；锑为９８～１１０％。A double-slotted atomic trapping quartz tube has been used to determine the cohtent of Sb and Ph in fog of powder. The influences of trapping time and acetylene flow onthe sensitivity were studied. The recoveries are determined and the results are satisfactory.
