Description
A new type of anion exchanger, consisting of porous silica particles containing benzimidazole groups as exchange sites, was manufactured for use in an advanced process for partitioning acidic nuclear waste solutions. Compared to conventional polymeric matrix anion exchange resins, this novel anion exchanger is characterized by rapid adsorption-elution kinetics, excellent stability in nitric acid media and significantly low pressure loss in a packed column. Adsorption performance of U, Pu, Np and various fission products onto this anion exchanger from HNO3 solution was investigated. In addition, the separation behavior of U and Pu from simulated spent nuclear fuel solutions was examined by column chromatography. Based on the research results, an advanced partitioning system that consists of anion exchange, electrolytic reduction and extraction chromatography has been proposed and evaluated. (authors)
