Abstract
The physicochemical properties on micellization of anionic surfactant, sodium dodecyl sulphate (SDS) and lithium dodecyl sulphate (LDS) in the presence of imidazolium-based ionic liquid 1-decyl-3-methylimidazolium tetrafluoroborate [Dmim][BF4] have been studied using surface tension and conductivity techniques. The interfacial and thermodynamic parameters have also been determined. FTIR has studied the aggregation behavior while aggregation number and Stern-Volmer constant is determined by fluorescence measurement. The current results indicate that the addition of [Dmim][BF4] to the anionic surfactant leads to a dramatic decrease in the CMC. The interaction of human serum albumin with micellar solution of SDS and LDS have been examined.
