Abstrakt: A low cost and selective method has been developed for the separation of trace concentrations of Y from its parent Sr. The proposed procedure is based upon complete retention of Y onto zirconium-vanadate (Zr-V) gel ion exchanger packed column from aqueous solutions containing HCl (1.0 × 10mol dm). Under these conditions, Sr species were not retained onto Zr-V sorbent. The retained Y species were then recovered with HCl. The performance of Zr-V sorbent packed column was determined via the height equivalent to the theoretical plates (HETP) and the number of plates ( N). Validation of the developed method was checked by calculating the radionuclidic purity in terms of purification factor (P = A/A) and radiochemical purity of the eluted Y from the column. Zr-V sorbent packed column offers unique advantages of retention and quantitative separation of Y from retention over conventional solid sorbents in rapid and effective separation of trace concentration of Y from Sr in their aqueous equilibrium media.
