Micellization of AOT in aqueous sodium chloride, sodium acetate, sodium propionate, and sodium butyrate media: A case of two different concentration regions of counterion binding

65 For AOT micelles the counter ion binding constant has values 0.40 and 0.82 below and above ∼0.015 mol kg−1 electrolyte concentration, respectively. The higher value of the counterion binding constant for AOT has been reported for the first time.
