Description

We report here a new method for the radiochemical purity evaluation of 105Rh complexes using a magnesium oxide adsorption technique. The principle of the technique is based on the quantitative adsorption of uncomplexed rhodium by magnesium oxide powder, leaving the complexes in solution. Cysteine and 4-benzyldiethylenetriamine were complexed with 105Rh and the radiochemical purity of the resultant complexes was evaluated by thin layer chromatography and magnesium oxide adsorption. The advantage of magnesium oxide adsorption over thin layer chromatography is discussed. (author)
