High-frequency electromagnetic field effect on the analytical signal of heavy metals ions in stripping voltammetry method using cells made of different materials has been studied. It has been found that there is the difference in the degree of signal increase for Zn (II), Pb (II) and Cd (II) ions under the influence of elcromagnetic field. It depends on the electrochemical cell material. The observed signals increase has been shown to be caused by the desorption of ions from the cell surface. The dependencies of anodic peak current of the ions of lead, cadmium and zinc on the frequency of high frequency electromagnetic field have been found. The research has shown the observed effects in HF field to be due to both surface and volume effects. Changes in the structure of the solution causes the increase in speed of delivery of ions to the electrode surface resulting in the increase of electrochemical reaction current. The desorption of ions from the cell surface leads to the increase of their analitical concentration in the solution which in turn raises the current.
