On negative retentions in organic solvent nanofiltration
Journal of Membrane Science, 2013Abstract Some recent literature reports negative retentions in organic solvent nanofiltration. However, this phenomenon is little understood and requires systematic evaluation. The aim of this work is to extend the systematic investigations of solute transport through a dense PDMS-based polymeric OSN membrane.

PEDOT:PSS Nanoparticle Membranes for Organic Solvent Nanofiltration
SmallAbstractRecycling of valuable solutes and recovery of organic solvents via organic solvent nanofiltration (OSN) are important for sustainable development. However, the trade‐off between solvent permeability and solute rejection hampers the application of OSN membranes. To address this issue, the poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (

Cellulose acetate membranes for organic solvent nanofiltration
2022Organic solvent nanofiltration (OSN) is a membrane-based sustainable alternative to conventional separation techniques because it is non-thermal and energy-efficient. The fabrication of membranes usually includes fossil-based polymers and toxic solvents that present significant challenges.

Mixed matrix membranes for organic solvent nanofiltration
Journal of Membrane Science, 2014Abstract Polyimide (PI) (P84) based organic solvent nanofiltration (OSN) membranes are well documented in the literature. One drawback of P84 based OSN membranes is the decline in the flux performance over time and with pressure. This is attributed to the compaction of the membrane top layer.

Organic Solvent Nanofiltration‐Supported Purification of Organocatalysts
ChemCatChem, 2015AbstractIn this study, the successful use of organic solvent nanofiltration for the purification of three highly enantioselective quinine‐based organocatalysts was demonstrated. Commercially available solvent‐resistant membranes (DuraMem series) were utilized to remove specific impurities that originated from their respective synthesis pathways ...

Sustainable manufacture of organic solvent nanofiltration membranes
2021Membranes are a robust, reliable and economical technology. However, polymeric membranes are manufactured from polymeric and organic solvent sources derived from petrochemical sources. The high volatile organic compounds (VOC) emissions of the organic solvents and the non-recyclability of the polymers often question the membrane manufacture ...

Towards predictive models for organic solvent nanofiltration
2018Organic solvent nanofiltration (OSN) is a promising technology for an energy-efficient separation of organic mixtures. However, due to the lack of suitable models that allow for a quantitative prediction of the separation performance in different chemical systems OSN is rarely considered during conceptual process design.

Experimental observations of nanofiltration with organic solvents
Journal of Membrane Science, 2001Abstract This paper reports the flux, retention and stability of nanofiltration (NF) membranes with aqueous and organic solvents, and three selected solutes having the same molecular weight of 350 Da: Orange II, Safranine O and Solvent Blue 35. It appears that the nominal manufacturer-specified molecular weight cut-off is only valid for predicting ...
