16th International Multidisciplinary Scientific Geoconference (SGEM 2016) -- JUN 30-JUL 06, 2016 -- Albena, BULGARIAWOS: 000391648800027The aim of this study was to prepare electrospun chitosan-based nanofiber mats and to incorporate the fruit extracts of Osage Orange (Madura Pomifera) into the mats. Chitosan-ethylenediaminetetraacetic acid/polyvinyl alcohol (CS-EDTA/PVA) was selected as the polymers. The osage orange extracts with 3 wt% were incorporated into the CS-EDTA/PVA solution and electrospun to obtain nanofibers. The morphology and diameters of the mats were analyzed using scanning electron microscopy (SEM). The chemical bonding properties were investigated by fourier transform infrared spectroscopy (FT-IR). Finally, the sorption potential of Osage Orange loaded nanofibers for the removal of common metallic pollutants, cadmium (Cd2+), cobalt (Co2+), copper (Cu2+), nickel (Ni2+) and lead (Pb2+) was also investigated. The results indicated that the diameters of the fibers were on the nanoscale and that no crystals of the extract were observed in the mats. Osage Orange loaded chitosan based nanofiber adsorbent presented good absorption capacity for all tested metals ranged between 29-34%. In conclusion, our experiments demonstrated that biomaterials composed of osage orange loaded CS EDTA nanofibers have a potential adsorbent for heavy metal.Bulgarian Acad Sci, Acad Sci Czech Republ, Latvian Acad Sci, Polish Acad Sci, Russian Acad Sci, Serbian Acad Sci & Arts, Slovak Acad Sci, Natl Acad Sci Ukraine, Inst Water Problem & Hydropower NAS KR, Natl Acad Sci Armenia, Sci Council Japan, World Acad Sci, European Acad Sci Arts & Lett, Acad Sci Moldova, Montenegrin Acad Sci & Arts, Croatian Acad Sci & Arts, Georgian Natl Acad Sci, Acad Fine Arts & Design Bratislava, Turkish Acad Sci, Bulgarian Ind Assoc, Bulgarian Minist Environm & Wate
