Composites of WO3-ZrO2 have been synthesized by Complex Sol-Gel Process developed in INCT and other techniques. Different proportions of metal oxides and temperature were applied. Elution profiles of columns filled with gel samples irradiated in nuclear reactor have been studied using as an eluent 0.9% NaCl solution. Purity of Re-188 fraction and efficiency of elution were determined. Ageing effect on elution efficiency was also examined. It was found that the best elution performance showed zirconium tungstate gel prepared in 110 A degrees C or 500 A degrees C in which molar ratio of metal oxides was 1:2.
