Abstract
In this study, 188-Re sulphide colloid was synthesized as a radiosynovectomy agent by reduction of sodium thiosulfate in the presence of perrhenate. The influences of the acidity, molar ratio and ultrasonic time on the colloid properties were investigated from 0.1 to 5 mol L-1; 5 to 70; and 10 to 60 min, respectively. The criteria for optimization of the influencing factors were the particle size and radiolabeling yield. Based on these factors the selected conditions were 1M HCl, thiosulfate to perrhenate molar ratio of 35 and 45 min for the ultrasonic time. The sizes of the particles were in the range of 1 to 5mm for more than 95% of the particles. The radionuclidic and radiochemical purity were found to be more than 99%. In addition, the synthesized colloid was stable for 5 days.
