Functionalized fibre yarn for capturing hormones from water solutions

Research output: Contribution to conferenceConference articleScientific

Abstract

In this work, was the porous cellulosic filament capable to capture hormone molecules from water developed. Hormone residues, in nature and drinking waters, have found to have many negative consequences for humans, livestock, and wildlife. These compounds have not been removed by conventional water purification systems, and thus they end up into rivers, lakes, and seas. In this study we investigated the porous cellulose fibre yarn with conjugated cyclodextrins (CD) for capturing 17α-ethinyl estradiol (EE2), a synthetic estrogen hormone used as contraceptive, from water. The fibre yarn was prepared by using wet-spinning from choline chloride-urea, deep eutectic solution, medium. The produced water tolerating fibre yarn had both high porosity and large swelling capacity. Cyclodextrin immobilization on cellulose and hormone capture reactions of the ready cyclodextrin-cellulose interface were verified by Surface Plasmon Resonance with cellulose ultra-thin films. The EE2 binding capacity of ready CD functionalized fibre yarn was found to be as high as 2.5 mg/g by UV-VIS absorbance solution tests. The developed material could find applications from inexpensive platforms in disposable affinity filtration.
