Simultaneous Removal of Calconcarboxylic Acid, NH4+ and PO43？ from Pharmaceutical Effluent Using Iron Oxide-Biochar Nanocomposite Loaded with Pseudomonas putida

In the current study, the Fe 2O 3/biochar nanocomposite was synthesized through a self-assembly method, followed by the immobilization of Pseudomonas putida ( P. putida) on its surface to produce the P. putida/Fe 2O 3/biochar magnetic innovative nanocomposite. The synthesized nanocomposite was characterized using different techniques including X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FT-IR). Then, the efficiencies of this material to remove calconcarboxylic acid (CCA) organic dye, ammonium ions (NH 4 +), and phosphate ions (PO 4 3？) from industrial wastewater were analyzed. The removal rates of up to 82%, 95%, and 85% were achieved for CCA dye, PO 4 3？, NH 4 +, respectively, by the synthesized composite. Interestingly, even after 5 cycles of reuse, the prepared nanocomposite remains efficient in the removal of pollutants. Therefore, the P. putida/Fe 3O 4/biochar composite was found to be an actual talented nanocomposite for industrial wastewater bioremediation. View Full-Tex
