Aqueous two-phase systems
(2019-01-01)
During the last 60 years, aqueous two-phase systems (ATPS) have been the focus of much research. A large number of studies have been reported on the characterization of these systems and their use on separation, analytic, ...

Development of a dispersive liquid–liquid microextraction method using a lighter-than-water ionic liquid for the analysis of polycyclic aromatic hydrocarbons in water
(Wiley VCH Verlag, 2016-11)
A dispersive liquid–liquid microextraction method using a lighter-than-water phosphonium-based ionic liquid for the extraction of 16 polycyclic aromatic hydrocarbons from water samples has been developed. The extracted ...

Liquid-liquid microextraction without phase separation in a multicommuted flow system for diltiazem determination in pharmaceuticals
(ELSEVIER SCIENCE BV, 2011)
Liquid-liquid microextraction without phase segmentation was implemented in a multicommuted flow system for determination of the anti-hypertensive diltiazem. The procedure was based on ion pair formation between the drug ...

Determination, characterization and modeling of aqueous biphasic systems composed of propylammonium-based ionic liquids and phosphate salts
(2020-09-01)
Ionic liquids (ILs)-based aqueous biphasic systems (ABS) are efficient platforms for the extraction and purification of biomolecules. To find more biocompatible ABS, propylammonium-based ILs, phosphate salts and water were ...
LC-UV Methodology for Simultaneous Determination of Lamivudine and Zidovudine in Plasma by Liquid-Liquid Extraction
(VIEWEG, 2009)
This study describes an accurate, sensitive, and specific chromatographic method for the simultaneous quantitative determination of lamivudine and zidovudine in human blood plasma, using stavudine as an internal standard. ...
