The present work is an investigation of the adsorption behavior of cesium(I) and europium(III) on zirconium molybdate at different pHs, different metal concentrations and different alcohol concentrations. The uptake percentages were found to depend on both the alcohol content and metal concentration. The effect of particle size with time was studied. It was found that the rate of adsorption of Cs(I) is chemically controlled and no diffusion along the particles takes place. In case of Eu(III) the particle size showed a marked effect on the rate of exchange.
