Abstract Most biogeochemical processes in natural waters take place at different phase discontinuities, among which the largest one is the atmosphere‐ocean boundary. Owing to molecular properties, surface active chemical species are adsorbed at natural interfaces, i.e. their concentration increases spontaneously. Electrochemical techniques offer the possibility of direct investigation of adsorption characteristics of a complex mixture of naturally present organic solutes at the electrode‐electrolyte interface. Among various possibilities of measurement the electrode double layer capacity changes at the mercury electrode found the widest application.
