摘要：

A novel, simple and inexpensive method for preparation of solid working electrodes from conducting refractory powder materials at room temperature in ambient atmosphere has been developed for electroanalytical purposes. The method is based on the use of a demountable device for hand pressing of the powder mixed with a polymer solution. During the process of pressing, the electric resistance of the electrode is controlled automatically. The electrodes from carbon powder, from titanium nitride and from carbon powder mixed with cobalt(II) phthalocyanine were prepared by this method. Results of voltammetric, stripping voltammetric and chronoamperometric studies showed a number of advantages of the prepared electrodes in comparison with conventional glassy carbon and carbon-paste electrodes.
