Thermodynamic Study of Amoxicillin and Naphthalene Adsorption on Activated Carbon Derived from Salvadora persica
Objectives: The pollution of aquatic bodies by Naphthalene and antibiotics effluent from activities of many industry is a significant environmental challenge affecting the ecosystem. Batch process was used to remove Naphthalene (NT) and Amoxicillin (AMO) with activated carbon prepared of Salvadora persica as adsorbent (ACSP). Methods: Batch studies were performed to evaluate and optimize the effects of various parameters such as contact time, temperature of the solution, NT and AMO concentrations and adsorbent dosage. The adsorbent characteristics were determined using SEM and BET technique. Results: The surface areas of ACSP and SP were 289.4 and 51.27 m2/g, for the adsorbents respectively. The equilibrium of the adsorption process was attained at 75 min adsorbent. The interaction of NT and AMO ions onto ACSP was spontaneously endothermic and it agreed with pseudo-second-order equation. Conclusion: This attempt has shown the potential of modified clay as a suitable eco-friendly sorbent for removing NT and AMO.
