The removal behavior of hydrous manganese oxide (HMO) and hydrous stannic oxide (HSO) were assessed for Cs(I) ions as a function of adsorptive concentration, temperature, co-ion effect and pH applying a radiotracer technique. A first order uptake of Cs(I) obeying the Freundlich adsorption isotherm over the entire range of the adsorptive concentration (10−2 to 10−8 mol dm−3) for Cs(I) is established. The temperature (303–333 K) dependence study showed that the Cs uptake to be endothermic and irreversible in nature proceeding through an ion-exchange type mechanism. HMO and HSO were found to be fairly radiation stable towards a 11.1 GBq neutron source (associated with a nominal γ-dose of 1.72 Gy/h) for the removal of Cs(I). The uptake of metal ions is affected to varying degrees by presence of some diverse co-ions.
