2-HBR负载树脂分离富集金的研究及其分析应用

The Investigation of Separation and Preconcentration of Au by 2 HBR Loaded Resin

本文探讨了２－羟基苄叉罗丹宁（２－ＨＢＲ）负载树脂对金的吸附性能及用ＡＡＳ吸附金的酸效应、吸附动力学、吸附机理、吸附热力学、动态试验等。

The adsroption behavior of 2 hydroxybenzal rhodamine(2 HBR) loaded resin for Au is discussed. The effect of pH,the adsorption rate,the adsorption isotherms of resins and their column conditions of application for Au are measured by flame atomic absorption spectrophotometry. The Au(Ⅲ) adsorbed on the resins can be eluted quantitatively using Na 2SO 3 solution.The seperation and preconcentration of Au(Ⅲ) in analogous water samples are established and recovery is satisfactory.
