Abstract: Nonionic surfactants
have been used
extensively in various
industrial applications such
as cleaning, personal care,
crop protection, paint
and coating, textile
finishing, emulsion stabilization, food
and leather processing.
In this study,
we have studied
the adsorption of three
nonionic surfactants of
alkyl polyglycoside, namely
commercial APG from
Cognis and APG produced
from glucose as
well as APG
synthesized from sago
starch, at fluid–fluid interfaces. The variation of
surface and interfacial tension with the concentration of surfactant in the
bulk was studied,
and the data
were fitted using
a surface equation
of state derived from the Langmuir isotherm. The
agreement between (c) data and Langmuir isotherm model was very good.
Keywords: adsorption,
air/water interface, interfacial tension, surface tension
