Summary: The complexation of tetracyclines with Fe species plays a significant role in the removal of tetracyclines by ferrate. Experimental results show that the complexation of tetracyclines with Fe3+ contributes to 79% of the overall removal, followed by oxidation (11%) and adsorption/flocculation (10%). Thermodynamic and kinetic calculations suggest that complexation reactions between Fe3+ and tetracyclines are more likely to occur than oxidation reactions between ferrate and hydroxyl radicals. The complexation rates of tetracyclines with Fe3+ determine the removal of multiple tetracyclines by ferrate, highlighting the importance of considering complexation in the removal of pollutants.
