| 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. 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. |
