Abstract :Adsorptive cathodic stripping voltammetric determination of aluminum at ng mL-1 levels in salt samples based on the metal complexation with Calcon insert ignore into journalissuearticles values(1-insert ignore into journalissuearticles values(2-hydroxynaphthylazo);-2 naphthol-4-sulfonic acid); and the subsequent adsorptive deposition onto a hanging mercury drop electrode was studied. Central composite design was used as a design method. Several chemical and instrumental parameters insert ignore into journalissuearticles values(pH, ligand concentration, deposition time, deposition potential, and complexing time); were involved in the experimental design. Analytical parameters such as repeatability, linearity, and accuracy were also investigated and the detection limit was found as 0.32 ng mL-1.
