Adsorption of cetyl trimethyl ammonium bromide (CTABr) at various interfacial in presence and absence of potassium chloride (KCl)

Abstract
Interfacial tension
measurements were made using AGLA micrometer
syringe (Burroughs Welcome) at benzene water, toluene water and air water
interfaces with varying concentration of cetyl trimethyl ammonium bromide in
presence and absence of potassium chloride. There was regular decrease in
values with increase in concentration of
CTABr. The
values in presences of KCI were less than in its
absence because surfactant ions were strongly adsorbed at interface owing to
the neutralization of repulsive ionic head group charge of surfactant ions.
From these data, surface pressure (π), surface excess (
s) and area occupied per
surfactant ion at various concentration have been calculated. The values of
s have been determined
from gradients ofDownload
