Semi-automated 86Y purification using a three-column system.
The separation of (86)Y from (86)Sr was optimized by a semi-automated purification system involving the passage of the target sample through three sequential columns. The target material was dissolved in 4 N HNO(3) and loaded onto a Sr-selective (Sr-Spec) column to retain the (86)Sr. The yttrium was eluted with 4 N HNO(3) onto the second Y-selective (RE-Spec) column with quantitative retention. The RE-Spec column was eluted with a stepwise decreasing concentration of HNO(3) to wash out potential metallic impurities to a waste container. The eluate was then pumped onto an Aminex A5 column with 0.1 N HCl and finally with 3 N HCl to collect the radioyttrium in 0.6-0.8 mL with a >80% recovery. This method enabled us to decontaminate Sr by 250,000 times and label 30 micro g of DOTA-Biotin with a >95% yield.
