Solvent resistant microporous/nanoporous polymeric hollow fiber and flat film membranes and their applications
The separation and purification of organic-solvent-based process streams may be carried out by membrane processes such as nanofiltration/ultrafiltration/microfiltration and membrane solvent extraction. Lack of solvent stability and chemical stability of most commercially available membranes is …

Development of multi-residue and selective methods for the ultra-sensitive determination of endocrine disrupting chemicals in aqueous samples
… multi-residue method is developed using sorptive extraction in combination with in-situ derivatization. Since the extraction of polar analytes is limited when using sorptive extraction with polydimethylsiloxane (PDMS), a novel type of sample preparation namely sorptive membrane solvent extraction, …

Characterization of microporous ECTFE membranes exposed to different liquid media and ?-radiation and nanoparticle microfiltration through such membranes
Microporous polymeric membranes are used in a variety of applications for separations, purification as well as barrier function. A major application is for microfiltration (MF). Changes in the properties of MF membranes exposed to acids, bases and organic solvents are of interest in semiconductor …
