Separation of Pharmaceutical Process-Related Impurities via an Organic Solvent Nanofiltration Membrane Cascade

The control of impurities is a critical issue in pharmaceutical industry and very strict regulations related with this issue have been introduced by ICH (International Conference on Harmonisation). The drugs impurities in general are classified into two types: (1) impurities associated with the Active Pharmaceutical Ingredients (API) production and, (2) impurities generated during formulation a...

Nanopapers for organic solvent nanofiltration.

Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can be manufactured as simply as producing paper? Here the production of nanofiltration membranes made from nanocellulose by applying a papermaking process is demonstrated. Manufacture of the nanopapers was enabled by inducing flocculation of nanofibrils upon addition of trivalent ions.

Nanofiltration (NF) membrane process with pre-ozonation for brine treatment

Separation and Recovery Process for Rare Earth Metals from Fluorescence Material Wastes Using Solvent Extraction

The separation and recovery of rare earth metals from fluorescence material waste was investigated by using solvent extraction with 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester in kerosene. Extraction equilibrium expressions were established for the trivalent metals (La, Ce, Eu, Tb, Y and Al) and divalent metals (Ca, Sr and Ba) for both single and multi components systems. The process s...

Solvent-resistant nanofiltration for product purification and catalyst recovery in click chemistry reactions.

The quickly developing field of "click" chemistry would undoubtedly benefit from the availability of an easy and efficient technology for product purification to reduce the potential health risks associated with the presence of copper in the final product. Therefore, solvent-resistant nanofiltration (SRNF) membranes have been developed to selectively separate "clicked" polymers from the copper ...
