Chemical polymerization of aniline modified Prussian Blue Analogues from an hydrochloric acid medium: Application in pollution adsorption for treatment of industrial wastewater

Prussian blue analogues (PBA) @ PANI nanocomposite (Co-PBA@PANI/Nc) adsorbent was synthesized via co-precipitation method by through in situ oxidative polymerization. The composite was characterized by XRD, FTIR, TEM and BET techniques. The XRD and FTIR patterns confirm the formation and insertion of Co-PBA in the backbone of PANI. The results of TEM revealed the formation of irregular particles with average size of 30 nm in diameter. The sorption studies of metal ions on composite cleared that the composite has affinity toward of Zn2+, Pb2+, Ni2+, Cd2+ ions. Co-PBA could enhanced the adsorption percentage of bare PANI amount up 50%.
