ABSTRACT:
A novel method for preparation of electrodes at a low temperature from electroconducting refractory powder materials. The electrodes are useful for analytical purposes. The method is based on cold pressing of the powders, wetted with solution of a polymer and placed into a disposable frame of the same polymer, with the help of a laboratory hand device producing a relatively small pressure. Control of the end of pressing is done by means of measurement of the electrode resistance. A puncheon serves as a current conductor. Electrodes thus prepared have a low resistance, a high sensitivity and stability. In comparison with glassy carbon electrodes, the most widely applied ones in electroanalytical chemistry, the novel electrodes are cheaper, yet not inferior to such glassy carbon electrodes, and even sometimes better. For example, an electrode prepared from titanium nitride powder has a wider anodic range of potentials and may be used for determination of compounds containing SH-groups, which is impossible to achieve with glassy carbon electrode.
