Abstract
A separation procedure of 64,67Cu(II) from 65Zn(II) was studied for serving 62Zn/62Cu generator preparation. The distribution coefficients of 65Zn(II) and 64,67Cu(II) ions from homogeneous medium of hydrochloric acid and acetone onto De-Acidite FF anion exchanger were investigated. Both hydrochloric acid and acetone concentrations are important factors that affect the separation process. Effects of decreasing the HCl concentration from 0.2 to 0.04Â M, increasing the acetone concentration from 5% to 80% and different acetone concentrations (5-97%) in 0.2Â M HCl were also studied on the separation of 64,67Cu(II) from 65Zn(II). The exchange capacity of Zn(II) on the De-Acidite FF matrix was obtained as 3.8Â meq/g and the64,67Cu(II) elution efficiency was 92.5% using 20Â ml of 0.2Â M HCl-60% acetone with flow rate of 2Â ml/min.The radionuclidic purity and radiochemical purity of the eluted 64,67Cu(II) were examined.
