Stability analysis of new composite Cerium Molybdate -polyacrylonitrile against irradiation with dose of gamma rays

This research work introduces a new method for synthesizing CER.M-PAN composite to be used as 137Cs absorbent from nuclear waste water. The granular morphology and crystal structure of the synthesized compound were determined using various methods such as IR, SEM and BET. The impact of important elements such as interfering ions in the uptake of cesium by the pellets and the temperature distribution was evaluated on distribution coefficient. It is shown how to use the synthetic adsorbent following Freundlich relations as well as performing as a multi-layer insulation. The cesium absorption performance of synthesis granules is very good due to its porous structure. The product stability against high doses of radiation (100-200kGy) was investigated. The cobalt-60 radiation source with gamma irradiation energies 1.17Mev and 1.33Mev is used. The result shows that the synthesized granules have a very good stability against radiation dose as 200KGy and maintains its original structure.
