This article focuses on electric filed influence on dynamic adsorption and desorption of different class water soluble surface-active matters (SAM). Non-iogenic alphend, cation-active Dmabakh and anionic-active sulfonic acid are used as SAM.
It has been defined the permanent current passing through solutions of these SAM doesn’t influence on value of their interphase tension on border with hydrocarbon liquid.
It has been determined adsorption activity of SAM on surface of quartz adsorbent depends upon current type.
Presence of permanent current value of maximum alphenol adsorption decreases while influence of alternating current on model increases adsorption.
Maximum adsorption of cation-active SAM on adsorbent surface can be observed by presence of permanent current and its minimum value – by lack of electric filed.
In case of anionic-active sulfonic acid field of alternating and permanent current provides growth of adsorption value.
In case of anionic-active sulfonic acid field of alternating and permanent current provides growth of adsorption value.
Desorbtion of molecule of non-ionogenic and anionic-active SAM increases under condition of permanent and alternating current while molecules of cation-active – practically never change.
