One is a biochar material namely PB1P15 derived from banana peels-plastic bottles composite and another is a magnetized biochar material namely PB1P15M synthetized by co-precipitation of iron III chloride hexahydrate (FeCl3.6H2O) and iron II chloride tetrahydrate (FeCl2.4H2O) of the aforementioned biochar. The two synthetized materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM-EDX), Fourier transformed infrared (FTIR) and Brunauer-Emmett-Teller / Barret-Joyner-Halenda (BET/BJH) techniques. The characterization analyses revealed successively, the appearance of reverse spinel groups of magnetite, elongation vibration of Fe-O bonds and specific surfaces areas of 83.03m2/g to 163.9m2/g for biochar (PB1P15) and diochar/Fe3O4 (PB1P15M) respectively. This prominence presence of iron oxides in the magnetite forms (Fe3O4) mainly on PB1P15M surface was used as catalyst for heterogeneous Fenton process for MB degradation. The photo-Fenton analyses tests indicated a strong degradation of MB of 69.7% in dark condition and up to 98.4% in the presence of UV light. These results were obtained under optimum conditions of 80mg/L and pH equals to 2 of MB solution, 0.2mg/L of H2O2 solution with 15mg of PB1P15M in one hour of contact time. Finally, the catalysts performances were tested by its recovery in MB solution through magnetic separation and reused three times without any loss of activated denoted.
