Resumo(1) The distribution of radon between various organic solvents and water has been determined at 25°C. Radon is always distributed better into the organic phase. The distribution constants of radon in these liquid-liquid partition systems are in the range from 25 to 80. (2) The distribution of radon between aqueous calcium chloride solution of various concentrations and carbon tetrachloride has been determined at 25°C. A remarkable salting-out effect for radon has been observed. (3) A solvent extraction method for the separation of radon from radium(II) and the decay products in aqueous solutions has been suggested.
