Gomez etal. [160] have studied specific adsorption of potassium penicillin G (salt K) on Hg electrode from electrocapillary and capacity measurements. The Frumkin isotherm has been found applicable to the quantitative description of the data repulsive interaction parameter equaled —3.5 and standard free Gibbs energy of adsorption at the zero charge was —38.6 kJ mol h depended linearly...

Close proximity between atoms leads to synchronization of their orbiting electrons. This causes the induction of dipoles that attract each other (London-van der Waals interaction). At closer approach, the electron clouds overlap, giving rise to repulsion (Born repulsion). The variation of the Gibbs energy of dispersion interactions Gji p between two atoms with their separation distance r is given by... 

FIGURE 20.7 Gibbs energy of adhesion of a particle at a brush-coated, charged substratum surface as a function of separation distance (—), made up of four types of contributions (1) short-range particle-substratum attraction (2) dispersive attraction (3) electrostatic repulsion due to overlap of Uke-charged electrical double layers and (4) osmotic repulsion due to compression of the polymer brush.
