Abstract

Abstract Polyacrylonitrile yarn hard waste and multiwall carbon nano-tubes nanofibrous mat was prepared by the electrospinning technique. The nanofibrous composite mats were characterized using thermo-gravimetric analysis, Fourier transform infrared spectroscopy, FT-Raman, scanning electron microscopy, and X-ray diffraction. Adsorption studies were conducted with various physical and chemical parameters such as contact time, solution pH and initial dye concentration. The maximum methylene blue dye removal efficiency of nanofibrous composite was found to be 73.4%at optimized pH 10. The pseudo-second order kinetics and Freundlich isotherm are suitable for methylene blue dye adsorption of nanofibrous composite.
