Abstract
The adsorption of small concentrations of radiothallium(III) on the cation-exchange resin Amberlite IR-120(H) begins to decrease at 8 and 32°C when the concentrations of hydrochloric and hydrobromic acids in the solution are about 10 −3 and 10 −2 and 10 −4 and 10 −3 M respectively. The adsorption of tracer thallium at 25°C on the anion-exchange resin Dowex 1-X8 is at a maximum when the concentration of hydrochloric acid in the solution is about 10 −1 and 1 M for the (III) and (I) oxidation states respectively. The presence of perchloric acid depresses markedly the adsorption of tracer thallium(III) on Dowex-1 from hydrochloric acid media.
