✦ Synopsis

Ahatraet-The adsorption uf dimethyl sulfoxide (DMSO) at the mercury/DMSO + 0.15 M Na,SO, interface is studied using the electrode charge density as the independent electrical variable and taking into account medium effects. In order to perform this analysis the mean activity coefficients of the salt in the presence of DMSO were experimentally determined and the electrical double layer parameters calculated by using Fawcett's function. The results suggest that upon adsorption the DMSO molecule, in the concentration range used, may suffer a partial reorientation process. The system can be described by Frumkin's isotherm but it is necessary to consider a variation of the maximum surface excess with the electrode charge.

The specific adsorption of penicillin G (salt K) on the mercury in aqueous solution has been determined from electrocapillary and capacity measurements. The adsorption of penicillinium anions can be fitted by a Frumkin isotherm with a value of -3.5 for the interaction parameter. The standard Gibbs e

## Abstract At concentrations higher than 2⋅10^−4^ M, and below pH 3, the cyclic voltammograms of picloram (=4‐amino‐3,5,6‐trichloropyridine‐2‐carboxylic acid) on Hg electrodes show two prepeak systems (named I and II attending to the proximity to the main reductions peak), which can be attributed
