The adsorption of ortho, meta and para isomers of aminobenzoic acid at Hg/1N HCl interface has been studied using capillary electrometer. All the three isomers are found to adsorb on both sides of electrocapillary curve. Adsorption is found to be more for the ortho isomer, followed by meta and para in the decreasing order. Thermodyanamic parameters like charge on the metal surface (q^M) and surface excess of organic molecule adsorbed (Torg) have been evaluated. The adsoption data for the isomers have been analysed thoroughly to choose the best fit of isotherm for each isomer and all the three isomers are found to obey Temkin’s adsorption isotherm. Free energies of adsorption for constant values of charge have been obtained for the isomers
