Abstract:

Salicylidene-o-aminophenol provides a sensitive spectrofluorimetric reagent for the determination of aluminium down to 27 ng (or 2.7 x 10(-4) ppm in the final solution). The most suitable conditions of pH (5.6), reagent concentration and development time (>20 min) have been established. Extraction with sodium diethyldithiocarbamate into ethyl acetate at the pH of the determination renders the method highly selective; out of 46 foreign cations examined only chromium(III), scandium and thorium interfere. Anions which form complexes with aluminium, such as citrate, tartrate and fluoride, also cause interference, but none of the common anions interferes. A 1:1 stoichiometry of the complex has been established and some conclusions have been drawn concerning its nature.
