Abstract:

Automatic continuous mixing (ACM) was used to collect light scattering data as the concentration of SDS/dopant in the solution was slowly changed. It can be seen that as the concentration of salt or as the ratio of Dopant:SDS is increased, the light scattering signal will change and then from this data different regions can be isolated and the existence of micelles and supramicellar assemblies can be identified.

Purpose:

To determine morphology changes in supramicellar aggregates of sodium dodecyl sulfate as concentration decreases below the critical micelle concentration.

Data Parameters and Units:

Definitions: time (s) I(sub)R_90 = intensity of scattered light from samples (units = cm^-1) salt concentrations are given in mM R = (mass of dodecanol/mass of SDS) SDS = sodium dodecyl sulfate surfactant SDS concentration (mg/ml)
