Stability analysis of MnO2-PAN absorbant of cesium-137 radionuclide against gamma rays

This research introduces a new method for the synthesis of composite granules. The major advantage of this composite granules is absorbing ion of undesirable elements from the flowing waters or wastes as well as being applied for removal of environmental pollution, specially 137Cs as one of the well-known elements which being released in the environment during nuclear accidents. MnO2-PAN is the new granular which was synthesized in this study. Some characteristics of the compound such as morphology and crystal structure were evaluated in various ways. The impact of important elements such as interfering ions in the uptake of cesium under various temperature and various cations was evaluated. It was shown that the synthetized adsorbent follows the Freundlich relations and performing as a multi-layer separation. Due to the porous structure and homogeneous distribution in the cross-manganese dioxide absorbent, the performance of granular synthesis for absorption of radionuclide cesium is good.
