<p>The inventive method consists in a potential concentration (deposition) of analysed components on a surface of a working electrode, a dissolution of a deposit in galvanostatic operation mode beginning with the value of electrode potential (U1) which corresponds to the initiation of the dissolution of the analysed component and finishing with the value of electrode potential which corresponds to the termination of the dissolution of the analysed component (U2); the second deposition in the galvanostatic operation mode for obtaining the electrode potential U1, and the dissolution for obtaining the electrode potential U2. The deposition and dissolution cycles in the galvanostatic operation mode and control of current value are repeated until the changes of time intervals of the deposition or the dissolution are terminated The concentration of the analysed component in a sample is defined in relation to the current value and the time intervals of the deposition and the dissolution for different cycles. In order to analyse other components, the operations are repeated at the corresponding values of U1 and U2.</p> |
