Micellar radii and high aggregation numbers in a 0.6 M NaCl sodium dodecylsulfate solution determined through positron annihilation lifetime spectroscopy

Article Abstract:

The equations to measure both the micellar average radius (R(sub mic) and aggregation number N(sub ag) using a simple technique, positron annihilation lifetime spectroscopy (PALS), are extended and applied to 0.25 M sodium dodecylsulfate (SDS) aqueous solution in the presence of large amounts of NaCl (0.6 M) as a function of temperature (T).

Effect of double bonds in the formation of sodium dodecanoate and sodium 10-undecenoate mixed micelles in water

Article Abstract:

The theory of mixed micellization is used for studying the micellization of an aqueous mixture of sodium dodecanoate (SDD) and sodium 10-undecenoate (SUD). The phenomenon is interpreted on the basis of the interaction between the vinyl group and water by hydrogen bonding.
