摘要
本文探讨了2-羟基苄叉罗丹宁(2-HBR)负载树脂对钯的吸附特性及其分析应用.根据吸附平衡的研究,探讨了树脂对钯的吸附反应机理.
The adsorption behavior of 2-Hydroxybenzal-rhodanine (2-HBR) loaded resin for Pd is discussed. The effect of pH, the adsorption rate, the adsorption isotherms of resins and their column conditions of application for Pd are measured by flame atomic absorption spectrophotometry.The Pd(Ⅱ) -adsorbed on the resins can be eluted quantitatively using (NH2)2CS solution. The separation and preconcentration of Pd(Ⅱ) in analogous water samples are established and recovery is satisfactory.
