Membrane-Extraction Technology's Memsorb uses a combination of adsorption and membrane filtration technology to effectively remove toxic transition metals, such as palladium, from process solutions.
Membrane-Extraction Technology (Met) has introduced the first of a string of successful applications to the OSN series of filtration processes for the fine chemicals and pharmaceuticals industry.
The new process, known as Memsorb, combines the best aspects of organic solvent nanofiltration with conventional adsorption techniques to remove greater than 99% heavy transition metals.
Memsorb uses the Starmem series of organic solvent nanofiltration membrane from Grace Davison.
These membranes provide exceptional performance in organic solvents and have molecular weight range cut-offs of 200, 220, 280 and 400Da.
Other potential applications for the Starmem range include solvent exchange, phase transfer catalyst recycle, organics recovery, product purification and impurity removal.
The key advantages of Memsorb include: efficient removal of heavy metal/toxic compounds, greater than 99.8 percent of the toxic compound in the process stream can be removed in a single pass; it is a simple process that can be carried out in less time and using less energy in comparison to distillation and other conventional methods; removal of the transition metal without compromising yield; prevent degradation of reaction mixtures; and it is a single pass technique that give consistent results every time.
