| Abstract: | Micellisation behaviour of mixed surfactants
of CTAB and Triton X-100 in the presence of isatin has been studied by surface
tension measurements over a wide range of Triton X-100 mole fractions and total
surfactant concentrations. The average
interaction parameter has been evaluated using Rubingh theory and found to be
-0.396 indicating synergistic behaviour in the mixed micelles. Kinetic studies
showed that the pseudo first
order rate constant increases with increase in mole fraction
of Triton X-100 at constant total surfactant concentration
and decreases with increase in total surfactant concentration at
constant mole fraction of Triton X-100. Kinetic analysis has been carried out
using a Berezin pseudophase model and binding
constants determined to explain the micellar effect. |
