Abstract
The study of radiochromatographic separations for the neutron activation analysis of trace level metals in fresh water sources is reported. Chromatographic separations of volatile metal-organic compound complexes were developed for post-irradiation separations. Quantitative elution from the chromatographic column of the complexes of Cr, Mn, Fe, Be, Lu, Gd, and Cu were studied and found to yield recoveries between 52 per cent and 98 per cent. Two additional fluorinated types of organic complexing agents were found to give quantitative recovery of chromium after irradiation. Extensive studies are reported which describe the optimum conditions for separation and account for decomposition and adsorption losses in the system.
