Electrochemical adsorption study of natural organic matter in marine and freshwater systems. A plea for use of mercury for scientific purposes

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. Due to its extreme toxicity mercury is on the list of the priority toxic chemicals and its production, use and distribution will be very limited in near future. In comparison to solid electrodes mercury has many advantages and particularly for adsorption study it is unavoidable because of the smooth, renewable and reproducible surface of the mercury drop. It is suggested that the use of mercury with all caution for scientific purposes should be implicit in new environmental regulations.
