Evaluation of Tetracycline Removal by Magnetic Carbon from Aqueous Solution: Insights into Characterisation and Adsorption Isotherms

Abstract

In our current research, an intriguing magnetic nanoporous sorbent activated carbon/copper ferrite (AC/CuFe2O4) composite was synthesized in the lab by co-precipitation technique. We used this magnetic activated carbon (MAC) for successfully removing tetracycline (TC) from water. We performed a number of experiments and studies to further support this, including the following: X-ray diffraction (XRD), Brunauer-Emmett-Teller surface area (BET), and vibrating sample magnetometer (VSM). Subsequent batch adsorption experiment evaluated the sorption performance of MAC on tetracycline, examining key parameter like temperature. An isotherm model reading revealed that the results of the experimental work were a good fit with the Freundlich model, showcasing a maximum adsorption capacity of 384.62 mg/g at 308K. The results proved that MAC exhibits an excellent sorbent for TC removal from aqueous solution.
