Abstract

In this work, nanotechnologies including electrospun nanofibers and nanoparticles were implemented for acid dye removal from simulated wastewater. Dynamic sorption properties of polyamide 6 nanofibrous membrane (PNM) were investigated, Titanium dioxide (TiO2) nanoparticles deposition was applied as surface modification method for PNM, and UV light was applied during the dynamic sorption process of C. I. Acid Orange 7 (AO7) on PNM. The light absorbance of influent and effluent were measured and the sorption capacity was calculated. The result shows improvement of sorption capacity after TiO2 nanoparticles (NPs) deposition and UV light applying. Long time UV lighting can improve the sorption capacity of AO7 on PNM with NPs but destroy the material.
