Abstract
The impedance method was applied to the study of the adsorption of maleimide, N-(p-aminophenyl)-maleimide, and N-(p-nitrophenyl)maleimide on a polycrystalline iron electrode in neutral and acidic media. It was found that the addition of maleimide and its derivatives to a sodium sulfate or a sulfuric acid solution, respectively, leads to the decrease of the iron double layer capacitance. It was shown that the adsorption of the substances investigated was described by Frumkin's isotherm. A correlation is found between the adsorption parameters, determined electrochemically, and the data obtained by quantum-chemical calculations.
