以RhCl63-为模板，丙稀酰胺(AM)为功能单体，甲基丙烯酸乙二醇酯(EGDMA)为交联剂，采用分子印迹技术合成了一系列铑离子印迹聚合物(IIPs)；研究了聚合条件和聚合方法对IIPs吸附性能的影响。结果发现，在模板、功能单体和交联剂的加入摩尔比为1：2：40时，用沉淀聚合法制备的铑离子印迹聚合物(IIP2)具有较高的吸附容量和最好的印迹效果。该印迹聚合物不仅可重复多次使用，而且在Rh(III)与Pd(II)、Pt(IV)、Ru(III)、Ir(IV)、Cu(II)、Ni(II)及Fe(III)之间的吸附选择性系数均在10以上，将其作为吸附材料用于分离富集添加了Rh(III)的河水样品中的Rh(III)，回收率在90%左右，相对标准偏差在5.0%以下。

Based on the molecular imprinting technology, a series of Rh(III) ion imprinted polymers (IIPs) were prepared in methanol by using RhCl63- as template, acrylamide (AM) as functional monomer and ethylene glycol dimethacrylate (EGDMA) as crosslinker. The effects of the polymerization conditions and polymerization methods on the adsorption property of IIPs were studied. The results indicated that Rh(III) ion imprinted polymer (IIP2) prepared by precipitation polymerization with the ratio of Rh(III), AM and EGDMA as 1:2:40 exhibits advantageous characteristics of higher adsorption capacity, optimal imprinting effect and good sorbent stability. The selectivity coefficients of IIP2 for Rh(III) over all of Pd(II), Pt(IV), Ru(III), Ir(IV), Cu(II), Ni(II) and Fe(III) are more than 10. The obtained Rh(III) ion imprinted polymer (IIP2) was successfully applied as a sorbent for separation and enrichment of rhodium from river water with the recovery of about 90% and relative standard deviation (RSD) of less than 5.0%.
