Metal-Polymer Sensors for Voltammetric Analysis

The way of the graphite electrodes production, modified by polymeric composition, containing nanoparticles of gold or mercury, for determination of metals’ ions by the method of stripping voltammetry is offered. The influence of copolymer’s structure, nature of solvent, concentration of metal-modifier, viscosity of composition, film’s thickness and conditions of its formation on electrochemical and mechanical characteristics of sensor systems was studied. The approbation of electrodes was carried out using the certified techniques with help of the method of stripping voltammetry during determination of zinc, cadmium, lead, copper, mercury, arsenic, selenium.
