In this study, high permeability flat sheet polysulfone nanofiltration membranes were prepared for amoxicillin (AMX) recovery from pharmaceutical wastewater. Membrane fabrication includes two steps: raw ultrafiltration membrane synthesis by phase inversion method and nanaofiltration membrane synthesis by surface photopolymerization. Raw ultrafiltration membranes were synthesized using different...

Technology makes the world go round . This statement is not only valid in general, but is also a true representation of the future of membranes in the field of the water treatment. Since their introduction in the late 1950 s, reverse osmosis, nanofiltration, ultrafiltration and microfiltration membranes have been increasingly used for a multiple of different applications in the field of water t...

Anion-adsorbing membranes provide an interesting possibility to remove toxic arsenate and chromate from drinking water. A promising way prepare anion-exchange materials is introduce positively charged amine groups on polymers. In this study, polyacrylonitrile (PAN) ultrafiltration were modified with functionalities the membranes. The success of modifications was demonstrated using infrared spec...

Although there have been no significant studies of the effects of different coupling chemistries, spacer arm length, or the nature of the functional group on the performance of ultrafiltration membranes, there is an extensive literature on these parameters in the field of chromatography. An optimal spacer arm ensures that the functional groups are placed a suitable distance from the surface of ...

An apparatus for the production of graded collodion membranes is described. The theoretical considerations of calibration are discussed in relation to the demonstrable structure and statistical characteristics of the membranes. A new definition of an "end-point" is suggested.
