Determinació espetrofotofluorimètrica de traces d'alumini amb àcid pamoic

A new spectrophotofluorometric method for the determination of
submicrogram amounts of aluminum with painoic acid in a dioxane:
water medium is described. The excitation and emission spectra for the
reagent and its aluminium complex, and the optimum conditions of pH,
reagent concentration and development time are studied, and the effect
of a large number of cations and anions on the aluminium determination
is investigated.

The stoichiornetry of the complex is obtained by the continuous
variations and mole-ratio methods. The conditional stability constant
for the complex is also evaluated.
