Determination and quantitation of Cu2+, Fe2+, Fe3+, Mn2+, and Al3+ metals in water samples using Wyn-CE capillary electrophoresis system and a direct UV detection using a PDC-based BGE.
L'avis de l'expert : Metal ctions were complexed by PDC and were detected under their anionic form. Monocharged cations were not detected.
