Abstract
Small angle neutron scattering has been used to elucidate the size and shape of a micelle in the sodium di-n-pentyl phosphate (DPP)-water system. The results are summarized as follows. For the DPP micelle, the aggregation number (n) depends on the concentration (n=12, at 7.0 wt% andn=15 at 10.0 wt%). The minimum micelle is spherical and has an aggregation numbern=7. For the DPP-micellar system, it can be assumed that micellar growth and variation from the spherical to probate shape occurs with an increase in concentration above the CMC.
