A scandium solution containing copper(IV) can be titrated photometrically in acid solution with (ethylenedinitrilo)tetraacetic acid (EDTA) in the presence of up to 60 times as much rare earth (on a molar basis). The absorbance of copper(IV)-EDTA at745 m mu is used a follow the course of the titration. Large amounts of aluminum (III), calcium (II), magnesium (II), uranium(VI). and significant amounts of iron(II) and other metal ions do not interfere. Bismuth(III), hafnium (IV), zirconium(IV), fluoride, and sulfate are the most importaant interferences. The sum of scandium(III) and thorium(IV) can be determined by this method. (auth)
