摘　　要：以浊点萃取-火焰原子吸收光谱法测定痕量铅,探讨了实验条件对浊点萃取及测定灵敏度的影响。在最佳条件下,铅富集倍数达到20倍。该方法可用于自来水、井水及河水中痕量铅的测定。The trace amount of lead in water was determinated by flame atomic absorption spectrometry after cloud point extraction. The chemical variables affecting the separation phase and extraction recovery were optimized, Under the optimum conditions,the enhancement factor was 20 for lead. The proposed method has been applied to the determination of lead in water samples with satisfactory recoveries.
