Innovative Magnetite Based Polymeric Nanocomposite for Simultaneous Removal of Methyl Orange and Hexavalent Chromium from Water

One of the most important directions for environmental remediation is effective removal dyes and toxic heavy metals from water using newly fabricated nanoadsorbents. Here, magnetic Fe3O4 nanoparticles were combined with nitrogen-containing functional group polymers chitosan (CS) polypyrrole (ppy) to synthesize a nanocomposite (polypyrrole@magnetic chitosan) useful removing methyl orange (MO) hexavalent chromium (Cr (VI)) water. The physicochemical properties determined SEM, TEM, XRD, FT–IR, TGA techniques. effect different factors on adsorption system was studied including contact time, pH, co-existed ions. kinetic study illustrated that fit well Langmuir isotherm. maximum capacity MO Cr (VI) found be 95 105 mg/g, respectively. reusability up five cycles 0.1 M NaOH as eluent slight decrease adsorbent efficiency. Furthermore, mechanism suggested via chemical reduction adsorption. This suggests ppy@magnetic promising nanoadsorbent
