The adsorption of carbamide and its aliphatic derivatives at the interphase mercury - electrolyte solution was studied, using the drop-time technique. The surface concentration *G of carbamide and its derivatives has been calculated for a wide range of concentrations at the selected potential. The shape of the electrocapillary curves indicates that both carbamide and its derivatives are adsorbed at the interphase mercury-electrolyte solution.
