Abstract
A rapid method to analyze the whole blood and its fractions for zinc content involving stripping voltammetery with the use of the modified thick-film carbon-containing electrodes is proposed. The method allows one to make the analysis free from metal mercury and its soluble salts, preliminary deproteinization of samples, and also to decrease the sample necessary for analysis to 5-50 ml. The measurable range of zinc concentration in blood and in its fractions is 100-20 000 mg/l.
