Abstract

The rare earth elements, including elements 57 through 71, provide many diverse series of studies through their chemical reactions. In as much as these elements are all in Group III of the periodic table, they are markedly similar in their properties. The separation, insulation and purification of the various rare earths from one another has long been a problem of great interest to the chemist. All of these elements show a principle valence of plus three. Cerium has a well-defined plus four state, stable in aqueous solution and europium forms a stable, insoluable divalent sulfate. Those two exceptions, however, are the only cases of valence states other than plus three which are stable under normal conditions. Consequently, procedures taking advantage of oxidation state differences cannot generally be used to effect a separation.
