Three forms of aluminium in aqueous systems determined by 8-quinolinolate extraction methods

Abstract

8-Quinolinolate extraction methods for the determination of Al³⁺ plus mononuclear hydroxyaluminium ions, polynuclear hydroxyaluminium ions, and the initial solid phase formed when a base is added to AlCl₃ solutions, are presented. The methods are based on the rates of reactions of 8-quinolinol with the 3 forms of aluminium substances. Results under a variety of experimental conditions are reported.
