Process optimization and modeling of lead removal using maleate/PAN nanocomposite nanofibers: Characterization, kinetics and isotherm studies

This study aims to investigate the efficiency of lead (Pb) adsorption by adsorbent maleate/polyacrylonitrile nanocomposite using immersing the pristine electrospun (PAN) nanofibers. Characterizations such as field emission scanning electron microscopy, transmission electron microscopy, and Fourier t...
