The Frumkin interaction parameter (AF) for the adsorption of a small series of aromatic compounds on mercury from ethylene glycol (EG) is accounted for in value and mainly in sign (always positive) using the dispersion energy contribution (εd) due to the mutual interaction among adsorbing aromatics molecules and that regarding EG molecules leaving the surface. A successful result is anyway obtained when the change of conformation of EG from the cis one in the adsorbed state to the cis-OH in the bulk phase (i.e., a conformation featuring an intramolecular OH bond) is considered.

Abstract
The Frumkin interaction parameter (AF) for the adsorption of a small series of aromatic compounds on mercury from ethylene glycol (EG) is accounted for in value and mainly in sign (always positive) using the dispersion energy contribution (εd) due to the mutual interaction among adsorbing aromatics molecules and that regarding EG molecules leaving the surface. A successful result is anyway obtained when the change of conformation of EG from the cis one in the adsorbed state to the cis-OH in the bulk phase (i.e., a conformation featuring an intramolecular OH bond) is considered.
