This research is devoted to the study of catalytic activity of cobalt and copper ions in the reaction of hydrogen peroxide decomposition under the action of the high-frequency electromagnetic field 1 Wt powered within 30-160 MHz. It has been stated that speed of the reaction substantially depends on the frequency of the imposed field. Our supposition is that the speed change of the indicated reaction under electromagnetic influence is related to the change in the speed of ligand exchange in the complex ion.

Key words: electromagnetic field, kinetics of reaction, catalytic activity.
