Abstract
The present work is concerned with the binding of the nucleotides (ATP, ADP) on the interface in hydrocarbon-water-CTAB and hydrocarbon-water-SDS (for ATP) model systems in the presence of Mg 2+ ions. It has been shown that magnesium salts of ATP and ADP, unlike free anions, bind with the interface in the hydrocarbon-water-CTAB system without affecting either the interphase tension value (σ) or that of the potential jump (Δψ). It has also been demonstrated that the binding of ATP with the interface in the decane-water-SDS system occurs only in the presence of Mg 2+ ions. On addition, a study has been made of the effect of the hydrogen ion activity on the binding of the ATP magnesium salt in the above systems. Model experiments indicated that there are at least two types of heterogeneous systems, in which the binding of the ATP magnesium salt with a charged interface is controlled by the hydrogen ion activity. In both cases studied, the rise in this activity causes desorption of the nucleotide salt from the interface.
