ABSTRACT Aggregation of the cationic surfactant cetyltrimethylammonium bromide
(CTAB) in water (W) and acetonitrile-water (ACN-W) mixtures of different
composition (10-20% (v/v) of ACN) was studied through fluorescence
measurements. The CTAB critical micellar concentration (CMC) and the
micelle aggregation number (Nagg) were determined at T = 22.0 °C. It was
found that for increasing volume ratios of ACN to W, the CMC value attains
a minimum (1.22 mM) at 15% (v/v) ACN while Nagg is continuously
decreasing as ACN content in the ACN-W mixture increases. The effect of
this dipolar aprotic solvent on the CTAB micelle formation can be interpreted
in terms of its considerably hydrogen bonding ability and influence on balk phase properties (solvophobic effect).
