Evaluating the charge of nanofiltration membranes
Journal of Membrane Science, 2001Abstract In this study, several methods were used to determine the charge of commercially available nanofiltration membranes, and were compared. First the ion-exchange capacity was determined by titration, this method is able to distinguish between positively and negatively charged functional groups on the membrane.

Separation potential of nanofiltration membranes
Desalination, 1990Abstract Nanofiltration has two interesting features: 1. - a fractionation capacity for different organic components in aqueous solutions, the ‘cut-off’ being in the range of 300 kg/kmol molecular weight 2. - the potential of realizing the Donnan-effect with respect to anions of different valency.

Microcystins removal by nanofiltration membranes
Separation and Purification Technology, 2005Abstract Microcystins produced by cyanobacterial blooms have been extensively found in water reservoirs used for drinking water abstraction and many conventional water treatment technologies have been reported to be ineffective for removing them. Safe barriers against microcystins in drinking water, are therefore, needed.
