Abstract

Aluminium is determined voltammetrically in the form of the aluminium complex with Acid Alizarin Violet N in an acetate buffer of pH 5.2 using a hanging mercury drop electrode and the d.c. or differential pulse technique. A linear dependence between the peak current and the aluminium concentration was obtained in the range from 2.10-8 to 5.10-6 mol l-1. The interfering effect of copper, lead and cadmium is eliminated by the auxiliary complex forming reagent-glycine.
