Abstract
Anodic stripping voltammetry has been developed for the simultaneous determination of copper (II) and lead (II) in environmental samples - drinking, lake and sea waters, sea lye and sea salt. The stripping peaks were obtained at -50 to -200 mV for copper and at -400 to -500 mV for lead ions, supporting electrolyte 0.01 M HNO3. The concentrate was stripped by changing the potential from -1300 to +400 mV, at a potential sweep rate 25 mV/s. The standard addition method was applied for the determination of the analytes. The concentrations of metals determined are below the international permissible limits and do not pose a health concern to use these natural objects in Bourgas region, Bulgaria.
Keywords: Voltammetry, Copper and Lead determination, Environmental waters, Lye and salt.
