摘　　要：研究了利用十二烷基磺酸钠（SDS）的增感作用，火焰原子吸收光谱法测定工业废水中微量铅。考察了各试验参数及共存元素对铅测定的影响，探讨了SDS增感机理。方法用于工厂废水中铅的测定，测定结果的相对标准偏差为0．8％～1．2%，检出限为0．11mg·L^-1，加标回收率为94%～104％。The sensitization effect of SDS on the FAAS determination of lead in industrial waste water was studied and its mechanism discoussed. Interferences of common co-exlsting elements and the working parameters of the method were also studied and optimized. Detection limit of the method was found to be 0.11 mg · L^-1. In the analysis of some substantial waste water samples. RSD＇s obtained were in the range of 0. 8%- 1. 2%, and recoveries were in the range of 94%-104%.
