Polyaniline hollow fibres for organic solvent nanofiltration
Chemical Communications, 2008Intrinsically-skinned asymmetric PANi hollow fibres, fabricated using a process of directly adding large organic acids to highly concentrated PANi solutions, show stability in a wide variety of organic solvents and have shown promising nanofiltration properties, giving high rejections of nanosolutes in acetone.

Recent Applications of Organic Solvent Nanofiltration
Chemie Ingenieur Technik, 2015AbstractCompared to other unit operations organic solvent nanofiltration is still regarded as a new one with its first commercial successes in the early 1990s. Since then a number of new applications and processes were developed that prove the potential of organic solvent nanofiltration as a resource‐efficient cold separation technology and enabler of ...

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.

Concentration of solutes by nanofiltration in organic solvents
Desalination, 2006Nanofiltration is a membrane process well controlled in aqueous separations. Its use to perform organic separations is currently studied by many researchers to understand the occurring transport phenomena. Some authors have underlined the great influence of trio membrane– solvent–solute on separation efficiency [1–3] but very few have performed ...

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) (

Retention of surfactants by organic solvent nanofiltration and influences on organic solvent flux
Separation and Purification Technology, 2016Abstract For the first time, the non-ionic surfactant Marlipal 24/70 was removed from 1-dodecene using organic solvent nanofiltration. Fluxes of up to 40 Lm−2 h−1 and retentions of more than 90% were achieved. The flux increase with increasing pressure was non-linear, whilst the retention increase appeared to be almost linear over the observed range.

Multicomponent mass transport in organic solvent nanofiltration with solvent mixtures
Journal of Membrane Science, 2014Abstract This work systematically investigates and models the retention behavior in organic solvent nanofiltration in solvent mixtures using a dense PDMS-based composite membrane. Experiments with n-alkanes as solutes with different chain lengths (142–339 kg kmol−1) were performed. The transport of these solutes is comprehensively quantified not only
