The different described procedures were based on the formation of the Al(III)-morin complex. UV–Vis spectrophotometry, spectrofluorimetry and differential pulse adsorptive stripping voltammetry (DPAdSV) techniques were compared under optimized experimental conditions. The DPAdSV method showed a better performance for the analysis of Al(III) in terms of capability of detection (70 nM) in comparison with the value obtained for UV–Vis spectrophotometric (300 nM) and spectrofluorimetic (110 nM) techniques. Thus, DPAdSV method was selected for the analysis of aluminium in river, tap and bottled water samples under the following optimized experimental conditions: pH = 4.4, deposition potential = +243 mV, deposition time = 210 s, giving satisfactory results. application/pdf eng Elsevier Talanta. 2019, V. 196, p. 131-136 https://doi.org/10.1016/j.talanta.2018.12.048 Attribution-NonCommercial-NoDerivatives 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Aluminium Morin Stripping voltammetry UV–Vis spectroscopy Fluorescence Water samples Química analítica Chemistry, Analytic Determination of aluminium using different techniques based on the Al(III)-morin complex info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Talanta 196 131 136
