| Abstract | ||||
| Ion exchange properties and radiation stability for synthesized hydrous tin, ferric and mixed Fe(III)-Sn(IV) oxides have been investigated. -These hydrous oxides were obtained by precipitation with ammonia from metal chloride solutions. The prepared samples were exposed to different doses of gamma radiation ranging from 1 MGy up to 5 MGy. The effect of various doses of gamma radiation on both the structure and ion exchange sorption has been studied. The structural features of non-irradiated and irradiated samples were investigated through I.R ,X-ray and surface area. No change has been observed in the structure of microcrystalline hydrous tin oxide as the gamma dose increases while hydrous ferric and mixed oxides showed slight changes. Sorption behavior for all samples was examined using mono, di, and trivalent cations. The capacity and kd values did not markedly altered with increasing gamma radiation dose for all the aforementioned oxides. It can be generally concluded that these oxides exhibit high radiation stability towards 7-radiation doses. | ||||
