Adsorption of organic substances at the mercury/ethylene glycol interface. Part 2.—Aromatic compounds

Abstract

The differential capacitance of a polarized mercury electrode in ethylene glycol solutions containing a series of aromatic compounds has been measured using a stationary drop. Adsorption has been investigated for benzene, toluene, phenol, aniline, dimethylaniline, dimethyltoluidine, diphenylamine, tribenzylamine and tribenzylammonium sulphate. The results are compared with those for adsorption of the same substances from aqueous solutions. The role of the non-aqueous solvent in determining the mode of adsorption is discussed.
