Title: Temperature dependent Surface and Fluorescence studies of the Industrially important Ionic surfactants with biologically important Amino Acids
Abstract:
The surface tension and fluorescence measurements have been carried out to study the interactions present between cationic surfactant, dodecyltrimethylammonium bromide (DTAB) and anionic surfactant, sodium dodecyl benzene sulfonate (SDBS) in aqueous solution, in presence and absence of additives (glutamine, histidine and methionine) at different composition and temperature. Critical micelle concentrations (CMCs) have been determined using surface tension measurement followed by Fluorescence measurement. In case of SDBS, the CMC value increases with rise in temperature while in case of DTAB, it shows a U-type behavior, meaning thereby, both hydrophobic and hydrophilic dehydration becomes prominent in case of DTAB while only hydrophilic dehydration plays decisive role for the micellization to take place in case of SDBS. Thermodynamic parameters of transfer, adsorption and micellization have also been evaluated and discussed in detail. Fluorescence probe study has been carried out to outline the results stated above. The CMC values calculated using pyrene as a fluorescent probe at room temperature resembles well with the micellar values determined using surface tension measurement.
