N2 - The thick-film modified graphite sensors (TMGE) as working electrodes are used for determination of heavy metals in bovine seminal plasma by anodic stripping voltammetry. The technique proposed is a very simple, express and no any sample preparation such as acid deproteinization or autoclave digestion is necessary. The sample of seminal plasma is just diluted with electrolyte solution in the analysis process. The aliquot of the sample is injected in the electrochemical cell and the analytical signal is measured. The analytical signal dependences on the accumulation potential, accumulation time and sweep rate have been studied. The standard addition method is used for calculating of heavy metal concentrations in the samples.
