Abstract:
1. A method for generating an eluate containing daughter isotope in ionic form from a parent/daughter isotope solution, said method comprising: a) providing an acid-treated glass adsorbent column, b) providing a loading solution by adjusting the isotope solution to a pH of above about 4.0, (c) adding N-methylglucamine to the loading solution to change the dielectric properties of the loading solution and increase the activity coefficient of the daughter isotope relative to the to the parent isotope to increase selective adsorption of the daughter isotope onto the column over the parent isotope, d) loading the column with the loading solution, e) rinsing the loaded column with water to elute off the parent isotope, and f) eluting the daughter isotope in a solution by rinsing the column with an acid solution.
