Preparation and characterization of poly aniline modified chitosan embedded with ZnO-FeO for Cu(II) removal from aqueous solution.

Poly aniline modified chitosan embedded with ZnO/FeO nanocomposites were synthesized using a precipitation method and applied to the removal of Cu(II) from aqueous solution. The synthesized nanocomposite was characterized by FT-IR, XRD, FESEM, TEM, EDS, TGA, BET and zeta-potential analyses. The adsorption batch experiments were conducted as a function of five effective parameters including pH, contact time, initial concentration of copper, temperature, and adsorbent dosage using a central composite design (CCD) in response surface methodology (RSM).
