Performance Based Evaluation of Industrial Grade Resins Duolite ARA-9366 and Duolite A-368

Ion exchange resins are used in several chemical decontamination or cleaning processes and in nuclear industries for removal of radionuclides.1–5 Nowadays, ion exchange resins are not only used for separation but also as catalysts. In the past decade, inorganic ion exchange materials have emerged as an increasingly important replacement or complement to conventional organic ion exchange resins. Nevertheless, in many cases, for specific physical and chemical reasons, organic resins cannot be replaced by inorganic ion exchangers, and thus organic ion exchange resins continue to be applied globally in various industries.1–5 Therefore, the development of new organic ion exchange materials for specific industrial and technological applications is a great challenge to present-day researchers. In order to bring about the efficient and economic application of ion exchange resins in various industrial processes, efforts are being continuously made to develop new ion exchangers.6–8 Development of ion exchange resins is usually followed by characterization to understand the performance of those resins in various technological applications.9–12 Although several techniques are available for the characterization of ion exchange resins,13–17 the radiotracer technique offers several advantages such as high detection sensitivity, capability of in-situ detection, limited memory effects and physico-chemical compatibility with the material under study.18
