Synthesis of multi-functionalized FeO-NH-SH nanofiber based on chitosan for single and simultaneous adsorption of Pb(II) and Ni(II) from aqueous system.

A multi-functionalized poly ether sulfone (PES)/ chitosan (CS)/FeO-NH-SH nanofiber was applied for single and simultaneous removal of Pb(II) and Ni(II) ions from water systems. The structure of nanofibers was evaluated using FTIR, FESEM, BET, BJH, TGA, EDX and XPS analyses. The characterization results showed that the structure of nanofibers was well maintained after adsorption process.
