Abstract
The mixed adsorption layers of n-butanol-m-toluidine and n-butanol-p-toluidine were studied and the surface excess of pure components and their mixtures was determined. The occurrence of synergetic coadsorption was observed. The rate constants of Zn(II) ion reduction were determined in 1 mol l-1 NaClO4 in presence of n-butanol as an inhibitor, m- and p-toluidine as accelerating substances and in their mixtures. It was found that the inhibiting or accelerating effect depends on the concentration of n-butanol and m- or p-toluidine. Compensation of these effects achieved at the concentration ratio of CBU : CpT ~ 35 and CBU : CmT ~ 85 in a wide concentration range is an evidence of toluidine predominance in the formation of a mixed adsorption layer.
