The isotope and ion exchange between uranates precipitated from the solution at 22--85.8 deg C and the ions of alkali metals reached equilibrium within 30 min. The isotope exchange between uranates of Na, K, Rb, and Cs with the equivalent quantity of the corresponding chlorides from the solutions is 21.68--83.38 and 28%, respectively. The degree of isotope exchange increases with increasing temperature. The ion exchange of lithium uranate with Na/sup +/, Rb/sup +/, and Cs/sup +/ drops in this order from 8 to 2% which, it is thought, is associated with the increasing difference of the ion radii. The ion exchange of sodium uranate with K/sup +/, Rb/sup +/, and Cs/sup +/ is 30, 20, and 30%, respectively; that of potassium uranate with Na/sup +/ and Cs/sup +/ is 40 and 30; and that of cesium uranate with Na/sup +/ and Rb/sup +/ is 20 and 64%, respectively.
