Abstract

ABSTRACT
.A radiochemical procedure for the separation of carrier-free 111In from cadmium target is described. 111In is produced produced by the bombardment of a natural Cd-111 target by proton particles. The separation is carried out by the difference in the sorption of indium, cadmium and copper on an activated carbon samples. Laboratory studies were conducted to evaluate and optimize the various process variables (shaking time, pH and effect of buffer). A quantitative determination of the adsorptive capacity of activated carbons to separated these metals was also determined. The distribution coefficients of the three elements onto different types of adsorbents were evaluated in 0.05M HCl and 1M acetate buffer at pH 4 to find the best conditions for separation of 111In isotope from Cd and Cu.
