This study demonstrates the extraction of jacalin from crude extract of jackfruit seeds using anionic surfactant based reverse micellar system, sodium bis(2-ethylhexyl) sulfosuccinate (AOT) in isooctane. Effects of various parameters, such as, NaCl concentration (0.05 – 1 M), pH of aqueous phase (pH 4 – 10), AOT concentration (5 – 150 mM), contact time (5 – 30 min) and phase volume ratio (0.5-5) on the transfer efficiency of jacalin was evaluated by changing one factor at a time (OFAT) while keeping the other parameters constant. A maximum of 83% of protein transfer was achieved after equal volume of organic and aqueous phase was stirred for 20 min using 20 mM AOT at pH 5 aqueous phase containing 0.1 M NaCl. The findings demonstrated AOT reverse micellar system as a promising and effective method to extract and purify jacalin from crude protein mixture.

The micro-polarity anisotropy behaviour across the aqueous phase of a SDS (sodium dodecyl sulphonate)–hexane reverse micelle (RM) relies on the SDS packing in the oil–water interfacial self-assembled surfactant structure of the RM.

In the present work an attempt has been made to extract ternary mixture of Basic Yellow-2 (BY-2), Basic Red-12 (BR-12) and Basic Blue-26 (BB-26) dyes from simulated textile effluent by solvent extraction using anionic surfactant Sodium Dodecylsulfate (SDS). This study proposes an efficient, fast, simple and effective microemulsion system for the removal of cationic dyes using reverse micelles of anionic surfactant from wastewaters. In this method, dyes are dissolved in aqueous phase and mixed with organic solvent in the presence of surfactant. The effects of the concentration of feed mixture (dye and surfactant), temperature, pH and salt concentration on extraction of dyes from aqueous phase have been studied after the complete separation of two phases. The method poses no environmental threat, so it is an eco-friendly way to treat dye house effluents.
