Chitosan-titanium oxide fibers supported zero-valent nanoparticles: Highly efficient and easily retrievable catalyst for the removal of organic pollutants

Abstract Different chitosan-titanium oxide (CS-TiO2-x, with x = TiO2 loadings of 1, 5, 10,15 and 20 wt%) nanocomposite fibers were prepared and kept separately in each salt solution of CuSO4, CoNO3, AgNO3 and NiSO4 to adsorb Cu2+, Co2+, Ag+, and Ni+ ions, respectively. The metal ions loaded onto CS-...
