Data on Purification Technology Reported by K. Niedergall and Colleagues (Removal of micropollutants from water by nanocomposite membrane adsorbers)

August 5, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Purification Technology have been presented. According to news reporting originating in Stuttgart, Germany, by VerticalNews journalists, research stated, "Nanoscaled spheric polymer adsorbers with a variety of chemical surface functionalities were synthesized by miniemulsion polymerization and inverse miniemulsion polymerization. The nanospheres were embedded in polyethersulfone (PES) matrices by a wet-phase inversion process to form nanocomposite membrane adsorbers."

The news reporters obtained a quote from the research, "The resulting membrane adsorbers were characterized by scanning electron microscopy (SEM), pore size measurements, water flux measurements and various adsorption experiments. The membranes can be classified as microfiltration membranes and have the additional capability to adsorb substances with various physico-chemical properties. The capability to adsorb compounds with various physico-chemical properties is implemented by embedding different nanoscaled adsorbers specific against the target molecules. In this work the target molecules bisphenol A, a hydrophobic compound, and penicillin G (potassium salt), a charged molecule, were adsorbed together on one membrane."

According to the news reporters, the research concluded: "The nanocomposite membrane adsorber concept allows the adaption of membrane properties to a given separation task by an adjustment of the amount and the proportion of various selective particles."
