Comprehensive Characterization of Activated Carbon Functionalized With Fe3O4 and L-Arginine

Activated  carbon (AC) is considered  to be one of  the most popular  and  widely used  adsorbents in water and wastewater treatment worldwide. Physical, chemical, biological modification methods are used to increase the adsorption capacity of activated carbon. In this study, the effects of chemical modification using  nitric  acid  and Fe3O4-L-arginine  on  the  structural  and chemical  properties  of  activated carbon  were investigated. Characterization analysis of AC modified with nitric acid and Fe 3O4-L-arginine was determined by scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET),  Fourier transform infrared spectrophotometer (FTIR) analysis. From the BET data, it is understood that the specific surface area of the prepared Fe3O4-L-arginine@AC is 249.83 m2/g and pore volume is 0.30 cm3/g.
