A generalization of work on the chemistry of francium carried out by means of Fr/sup 212/ is presented. Methods for recovery and isolation of francium isotopes are considered. Co-precipitation of Fr/sup 212/ with various precipitates is studied. Most extensive are studies on co-precipitation of francium, cesium, and rubldium with di- and tri-heteropoly acids. Volatilities of tracer quantities of francium and cesium chlorides are studied as a function of temperature and time of heating. Detailed investigation is made on the sequence of adsorption of francium, cesium, and rubidium cations on KU-1 and KU-2 cation exchangers from electrolytic solutions of different concentrations. A new method of rapid and effective isolation of francium from cesium and rubidium is worked out. The possibility of using Fr/sup 223/for the determination of actinium in uranium ores is shown.
