摘要
This paper described the utility of tetragonal nano-zirconia (t-ZrO2) to remove trace levels of Cs-134 and Cs-137 contaminants from I-125 solution obtained from neutron irradiation of natural Xe target. A careful scrutiny of the adsorption parameters of t-ZrO2 was considered worthwhile investigating to arrive at the optimum conditions to perform the purification as well as concentration of I-125 solution. The procedure proposed herein provides I-125 of acceptable purity and radioactive concentration for clinical application. The compatibility of the separated product in the preparation of I-125 brachytherapy sources was found to be satisfactory.
