ABS>It is established that Ce and La form MeKFe(CN)/sub 6/type compounds with STAFe(CN)/sub 6/!/sup 4-/ and Me/sub 2/(C/sub 2/O/sub 4/)/sub 3/ with STAC/ sub 2/O/sub 4/!/sup 2-/, which can be determined by potentiometric titration using quinhydrone, antimony, and glass electrodes paired with saturated cathode electrolyte. Elements that are precipitated by the above reagents or form complex compounds with them impede the determination. The accuracy of the determination is equivalent io that of the gravimetric method of precipitating rare earthts in the form of oxalates.
