中文摘要：

以自合成的氨基吡啶（ANA）树脂为吸附剂，研究其对单组分重金属离子的吸附行为和在双组分体系中对目标重金属离子的分离去除能力。单组分静态吸附实验结果表明，在pH值为5条件下，ANA树脂对Cu（Ⅱ）和Ni（Ⅱ）的吸附容量分别达到1．022mmol／g和0．446mmol／g。静态吸附等温线和动力学过程可采用Langmuir方程和Lagergren二级动力学方程进行拟合。在Cu（Ⅱ）／Ni（Ⅱ）双组分体系下，Cu（Ⅱ）的吸附量较单组分大，高浓度Ni（Ⅱ）条件下，Cu（Ⅱ）在ANA树脂上具有更好的吸附选择性能。前222BV、248BV出水中，Ni（Ⅱ）纯度分别高达100％、99．999％，经简单浓缩处理即可进行回收利用，为树脂在高纯金属制备技术中的应用提供理论指导和技术支持，同时在有色金属资源的深度提纯和高级应用中具有重要的经济和战略意义。

英文摘要：

Polymeric resin containing 6-aminonicotinic acid （ANA resin） was prepared to study the selective adsorption behaviors for Ni（Ⅱ） and Cu（Ⅱ） in single-component solution and double-component mixture solution. In the experiment of single-component adsorption, the results of adsorption isotherms indicated that the total sorption capacity was 1.022mmol/g for Cu（Ⅱ） and 0.446mmol/g for Ni（Ⅱ） at pH 5. The static equilibrium data were in accordance with Langmuir equation, which showed that the adsorption of heavy metal ions on ANA resin was monolayer adsorption. The kinetic date could be well predicted by Lagergern- Pseudo-second-order equation. The results of competition experiment implied that the adsorption of Cu（Ⅱ） was not inhibited by Ni（Ⅱ） and the selectivity toward Ni（Ⅱ） onto the ANA resin was excellent in high concentration of Ni（Ⅱ） in mixture system. The total purity of Ni（Ⅱ） in the first 222BV and 248BV effluents could approach to 100% and 99.999% as performed in the column experiment, so that the heavy metal ions could be recovered and used through simple concentration process. The application of high selective resin tbr separation or purification is of great practical significance considering the scarcity of such resources.
