Abstract:
In this study, in the first step, active carbon synthesis using agricultural wastes (almond shells), with the aim of producing adsorbent with meso holes, had the highest surface area and the highest desired yield. For this purpose, the chemical activation method was used. In the second step, the synthesis of nickel ferrite nanoparticles (NiFe2O4) was considered by green, low cost and fast methods. For this purpose, solvent free combustion method was used with the help of microwave waves. In this method, glycine was used as a fuel, as well as oxidizing ammonium nitrate. This reaction was completed within a maximum of 30 min. In the third step, the synthesis of carbon nanocomposite with nickel ferrite was desired. For this purpose, ultrasonic bath technique, which is a quick method and reported for the first time, was used. The purpose of composite activated carbon with nickel ferrite nanoparticles was to create magnetic properties in carbon and increase the catalytic properties as well as self-cumulative self-immobilization of nickel ferrite magnetic particles. FT-IR, XRD, SEM, EDX, VSM and BET techniques were also used to identify products. Finally, the application of activated carbon, nickel ferrite nanoparticles and synthesized composite as a catalyst in the adsorption of organic dye from malachite green (MG) were studied and analyzed.
