Abstract
The spectrofluorimetric method previously described for determining scandium and based on the use of salicylaldehyde semicarbazone as reagent has been modified by incorporation of a solvent extraction separation procedure to permit the determination of scandium in the presence of the few other ions that also produce fluorescent species, i.e., aluminium, yttrium, etc. Chromium(III), titanium(IV) and zirconium produce low results, while tellurium(IV) and tin(IV) completely suppress the fluorescence of the scandium complex.
