ABSTRACT:
The removal behavior Hydrous Manganese Oxide (HMO) and Hydrous Stannic Oxide (HSO) were assessed for Cs(I) ions as a function of adsorptive concentration, temperature and pH. It was observed that an increase of these parameters enhanced the removal of Cs(I) ions from aqueous solutions. First order uptake of Cs(I) obeys the Freundlich adsorption isotherm (10-2-10-8 mol dm-3). The study on temperature (303 K to 333 K) dependence showed that the endothermic type of uptake proceeds by an ion–exchange type mechanism. Moreover, the HMO and HSO were found to be fairly radiation stable towards a 11.1 G Bq neutron source (associated with a nominal ?-dose of 1.72 Gy/h) for the removal of Cs(I). The uptake of metal ions are affected to varying degrees by presence of some diverse ions.
