in the present Research, in order to access new technologies eliminate radioactive contamination have been carried out . The construction and use of exchange resins with high efficiency and efficacy , as a new approach in research and practical method of separation is introduced. This project is one of the most important pieces of 137Cs radioactive decontamination nuclear fission , two new composite entitled as CER.M-PAN ( cerium molybdate - poly acrylonitrile ) and HCFC-PAN ( Cu Hegzacyanoferrat II- poly acrylonitrile ) was prepared their performance was evaluated in terms of continuous and discontinuous . To identify the structure of the synthesized compound , infrared spectroscopy techniques were used. Surface Area and Porosity of adsorbent beads were assayed . In order to increase the efficiency of these two composites , combining them with the PAN were prepared and their stability in different environmental conditions assessed and evaluated . ‌ The results suggest that the same efficiency than HCFC-PAN composite composite is CER.M-PAN .

Keywords: separation, H.C.F.C-PAN, 137Cs, Ion exchange, CER.M-PAN
