The coprecipitation of cerium(III) with uranium(IV) oxalate is studied using dimethyl oxalate to precipitate uranium(IV) from homogeneous solution. A limited study is also made using scandium(III) and uranium(IV). These systems obey the logarithmic distribution law more closely than the homogeneous distribution law. The distribution coefficient is found to be functionally related to the experimentally determined first-order precipitation rate constants when a trace quantity of cerium(III) is coprecipitated with carrier uranium(IV) oxalate. The coefficient trol migration is found to be equal to K/K where K, the fractional rate of precipitation of tracer, is determined in the presence of the carrier. The cerium (III) -uranium(IV) oxalate system obeys a distribution law modified to include ion charge rather than the unmodified Doerner-Hoskins logarithmic distribution law. (auth)
