No serious interferences from Zn, Fe, Cl and V were found. Small amounts of Ca enhanced the analytical signal. Electroactive or ionic aluminum concentrations in fresh waters sampled both from China and USA was analysed. %X Application of the adsorptive stripping voltammetry using DAS A (1, 2-dihydroxy an-thraquinoine-3-sulfonic acid) in the buffer solution of triethanolamine (pH 7.6) to determine the ionic forms of aluminum in fresh waters were presented in this paper.
