Separation of palladium metals is possible with the use of synthetic adsorbent resins. Two types of adsorbents based on a macroporous styrene-divinylbenzene copolymer were prepared by amination with phenylenediamine and impregnation with benzimidazole solution. A higher Pd(II) adsorption capacity on the aminated resin derivative was obtained in nitric acid solution than that on the conventional anion-exchange resins, such as Dowex 1x8-400 and IRN-78. The functional impregnated resin was found to have a superior distribution coefficient value of Pd(II) with about 14000 mL/g while the aminated resin had only about 700 mL/g. From this preliminary study, functional impregnated resin was shown to have good potential applicability for precious metal recovery as adsorption media from the spent fuel.
