Abstract

Background and Objective: Extreme use of antibiotics and discharging them to the environment lead to serious consequences. Activated carbon is the most commonly adsorbent for these contaminants but its main drawback is difficulty of its separation. The objective of this study was synthesis of MAGNETIC ACTIVATED CARBON by Fe3O4 and investigating its efficiency in adsorption of AMOXICILLIN from synthetic wastewater.Materials and Methods: Materials and Methods: Physical and structural characteristics of the adsorbent synthesized were analyzed using SEM, TEM, XRD and BET techniques. The effect of factors like pH, initial concentration of AMOXICILLIN and adsorbent, contact time, and temperature were investigated to determine thermodynamic parameters, equilibrium ISOTHERMs, and kinetics of ADSORPTION PROCESS.Results: Physical characteristics of the magnetized activated carbon showed that Fe3O4 nanoparticles had the average size of 30-80 nm and BET surface area was 571 m2/g. The optimum conditions of adsorption were: pH=5, contact time=90min, adsorbent dose of 1g/L and temperature 200C. The equilibrium ISOTHERMs data showed that the ADSORPTION PROCESS fitted both Freundlich and Longmuir models with the maximum capacity of 136.98 mg/g. The kinetic of the ADSORPTION PROCESS followed pseudo second-order model. The negative values of ∆H0 and ∆G0 obtained from studying the adsorption thermodynamic suggested that AMOXICILLIN adsorption on MAGNETIC ACTIVATED CARBON was exothermic and spontaneous.Conclusion: The present study showed that the MAGNETIC ACTIVATED CARBON has high potential for adsorption of AMOXICILLIN, in addition to features like simple and rapid separation. Therefore, it can be used for adsorption and separation of such pollutants from aqueous solutions.
