Organic micropollutants such as steroid occur in water in increasing quantities from predominantly anthropogenic sources. The functionalization of nanofibers with cyclodextrins (CD) is extremely interesting since such nanofibers containing CD molecules can potentially act as an efficient molecular filter by combining the specific complex formation with organic compounds with the very high surface area of the nanofibers. However, membranes from PES-CD are water-soluble. Therefore, the surface of cyclodextrin has been modified to avoid the leaching of cyclodextrin molecules from the nanofiber surface.
The aim of this project is to develop and characterize these membranes i) for water permeability, ii) micropollutant adsorption, iii) breakthrough behaviour. Based on the variation of a number of water quality parameters interaction mechanisms can be understood and the potential micropollutant uptake capacity estimated.
