A Biopolymer-based Nanocomposite as a Multifunctional Sustainable Material for Water Pollutants Degradation

 Abstract — Currently, the nanotechnology adsorption method is regarded as the most promising method for water decontamination. Among nanomaterials adsorbents, biopolymer-based nanocomposite materials have attracted significant research attention because they possess multifunctional properties beneficial for removing different types of pollutants from wastewater. Therefore, the main focus of this study is to synthesize and characterize a biopolymer-based nanocomposite, i.e., phosphorylated chitosan cross-linked multiwalled carbon nanotubes doped silver-titanium dioxide nanoparticles (pCh-MWCNTs@Ag-TiO 2 ). The biopolymer nanocomposite was synthesized using combined phosphorylation and cross-linking polymerization methods. Then, it was characterized using thermal gravimetric analysis, a range of spectroscopy, and microscopy techniques. The developed pCh-MWCNTs@Ag-TiO 2 will be used as a potential multifunctional nano-sorbents for the simultaneous removal of diverse pollutants from
