阴离子交换法从辐照后的Ni靶中分离64Cu
Chemical Separation of 64Cu From Irradiated Ni Target by Anion Exchange Method
摘要
Abstract
To separate 64Cu from cyclotron irradiated 64Ni target, a radiochemical purification procedure for "Cu from Ni and Co via anion exchange was developed. Based on the distribution coefficient data of Cu, Ni and Co between AG1-X8 resm and HCl medium, separation of 61Cu from Ni and Co using AG1-X8 anion exchange resin column had been studied with different concent rat ions of HC1 as the eluent. The Ni fraction was eluted by 6 mol/L HCU and Co fraction by 4 mol/L HC1. 64Cu fraction was washed out and collected in 1 mol/ L HC1. Recovery yield of 64Cu was 87. 5% ±3. 0%. The radionuclide purity of 64Cu produced by enriched 64Ni was higher than 99. 0% and the concentrations of Ni and Co in the final 64CuCl2 solution were both less than 0. 05 mg/L.关键词
