| 摘 要： | 基于5-Br-PADAP与镉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镉的新方法。镉的浓度在0.25～4.00μg/mL内呈线性,检测限为6.7μg/L;相对标准偏差（n=11）为2.7%,加标回收率为98.5%～102.3%。

| Abstract: | A new atomic absorption spectrometry after cloud point extraction method for the determination of trace cadmium was developed.The method was based on the fact of cloud-point extracted chelate engendered by 5-Br-PADAP and cadmium.The linear range for the determination of Cd2+ was cCd(Ⅱ)=0.25～4.00 μg/L and the detection limit found was LCd(Ⅱ)=6.7 μg/L and RSD(n=11) was 2.7%.The values of recovery of Cd in natural water samples were 98.5%～102.3%. |
