EVALUATION OF THE USE OF ANIONIC/ NONIONIC MIXED MICELLES IN REVERSED PHASE LIQUID CHROMATOGRAPHY OF CHLOROPHENOLS
The use of aqueous mixed micellar system consisting of sodium dodecyl sulfate (SDS) and polyoxyethylene (23) dodecanol (Brij-35) as the mobile phase in reversed-phase liquid chromatography was studied. A group of chlorophenols was used as the test mixture. Adding organic modifier to the system showed that the use of low concentrations of organic additives improves efficiency in SDS/Brij-35 mixe...
متن کاملProtein extraction using reversed micelles
Proteins can be extracted from an aqueous phase into reversed micelles. This transfer is governed by electrostatic interactions, for protein and surfactant have to bear opposite charges. The presence of high salt concentrations diminishes the attractive interactions and can lead to expulsion of the solubilized proteins. This is used to recover extracted proteins. Larger proteins require a large...
متن کاملReversed-phase Salt Assisted Liquid-liquid Extraction: A New Technique for Preconcentration and Determination of Crocin in Herbal Medicines by HPLC
A reversed-phase salt assisted liquid-liquid extraction (RP-SALLE) method was developed for the preconcentration and determination of trace crocin in herbal medicines by high-performance liquid chromatography (HPLC). In developed method, the roles of the aqueous and organic phases are inverted so that the analyte is extracted from the organic into the aqueous phase after salt addition and phase...
