✦ Synopsis

The adsorption of M-naphthalenesulfonate, B-naphthalenesulfonate and 1, 5-naphthalenedisulfonate ions on mercury from an aqueous solution at constant ionic strength has been investigated by measurement of the double layer capacity as a function of concentration. The adsorption can be represented by virial form of isotherm with a non-linear charge dependence of the standard free energy of adsorption. The influence of n-bonds, number and position of sulfonic groups in the aromatic ring on the adsorption parameters has heen considered.
