Adsorption of some mixtures of surface active substances at the mercury electrode: Kalousek commutator measurements

Adsorption behaviour at the mercury electrode of some mixtures of surface-active substances, relevant and important for natural and polluted seawater, has been studied on the basis of capacity current measurements using the polarographic method of discontinuously changing potential known as the Kalousek commutator technique.The total adsorption effects of different mixtures of selected surface-active substances (albumin, lecithin, oleic acid, Triton-X-100, sodium dodecyl sulphate) were determined in the seawater as a supporting electrolyte and compared with the values calculated from the individual isotherms.
