ADSORPTION REGION OF A CONDENSED 1-HYDROXYADAMANTANE LAYER AT THE MERCURY ELECTRODE-SOLUTION INTERFACE AS A FUNCTION OF TEMPERATURE

The temperature dependence of an adsorption of a 1-hydroxyadamantane c ondensed layer at 20-80 degrees C on the mercury electrode in solution s of Na2SO4 and NaF is analyzed with the aid of a relationship connect ing the shift of the adsorption-desorption potential with adsorption p arameters of the surface active organic substance (SAOS), its concentr ation, and the temperature (the relationship was derived earlier on th e basis of the Frumkin adsorption model), The magnitude of the desorpt ion potential is found to be related to adsorption parameters of SAOS and the changes in some of them with the temperature. It is shown that , in concentrated supporting electrolyte solutions, the weakening of t he salting-out effect of electrolytes occurring with the growing tempe rature should be taken into account.
