| 摘 要： | 基于5-Br-PADAP与铅形成稳定的螯合物能被TritonX-114浊点萃取的事实,建立了浊点萃取-原子吸收法测定水中微量的铅的新方法。铅的浓度在0~30μg/mL内呈线性,检测限为1.7 ng/mL;相对标准偏差（n=11）为2.7%,加标回收率为97.5%~102.5%。

| Abstract: | A new atomic absorption spectrometry after cloud point extraction method for the determination of trace lead was developed.The method was based on the fact of cloud-point extracted chelate engendered by 5-Br-PADAP and lead.The linear range for the determination of Pb2+ found was C(Pb(Ⅱ))=0~30 μg/mL and the detection limit found was L(Pb(Ⅱ))=1.7 ng/mL and RSD(n=11) found was 2.7 %.The values of recovery of Cd in natural water samples were ranged from 97.5 % to 102.5 %. |
