چکیده انگلیسی
The adsorptive cathodic stripping voltammetry technique (AdCSV) is used to determine copper(II) using salicylaldehyde thiosemicarbazone (N, S- donor) as a complexing agent on hanging mercury drop electrode at pH 9.3. Variable factors affecting the response, i.e. the concentration of ligand, pH, adsorption potential and adsorption time are assessed and optimized. The adsorbed complex of copper(II) and salicylaldehyde thiosemicarbazone gives a well defined cathodic stripping peak current at â0.35Â V, which has been used for the determination of copper in the concentration range of 7.85Â ÃÂ 10â9 to 8.00Â ÃÂ 10â6Â M with accumulation time of 360Â s at â0.1Â V versus Ag/AgCl. This technique has been applied for the determination of copper in various digested samples of whole blood at trace levels.
