Abstract

Adsorption behavior of Eu³⁺ on granulated a-zirconium phosphate (α-ZrP) has been studied by batch and column methods. The distribution coefficients (K_d) of Eu³⁺ into α-ZrP increased with equilibrium pH, suggesting ion-exchange adsorption. The K_d values were in the order of Eu³⁺>Cs^+>Sr²⁺>Co²⁺>Na⁺. An expansion of interlayer distance of α-ZrP in the presence of Na⁺ enables the large hydrated Eu³⁺ ions to be adsorbed on this exchanger, and the adsorption isotherm of Eu³⁺ ions followed Freundlich's adsorption formula. The granulated α-ZrP has high thermal stability and acid resistance. The breakthrough capacity for Eu³⁺ linearly increased with pH of the effluent.
