Abstract
Aqueous solutions of nonylammonium chloride (NAC) containing sodium ch loride were studied by using light scattering and small-angle neutron scattering (SANS) techniques. It was found that the aggregation number of NAC is independent of the surfactant concentration and increases s moothly with increasing the ionic strength. Micelles of NAC in D2O wit h [NaCl] = 0.3422 have prolate ellipsoidal shape and their average agg regation number is greater than that found in H2O at the same ionic st rength. A possible explanation of this difference may arise from a sol vent effect.
