Abstract
Two-dimensional MXene materials are attracting attention as nanoadsorbents for the removal of heavy metals from aqueous media. The adsorption properties of the magnetic composite Ti3C2Tx/Fe3O4 are investigated in relation to Fe(III) ions. It is found that the sorption capacity is 64.5 mg/g at a composite concentration of less than 10 mg/L. The kinetics of sorption is best described by a pseudo-second-order model, which indicates a chemical interaction between the sorbent and the sorbate. The calculated conditional activation energy (–17 kJ/mol) confirms that the sorption rate is limited by the diffusion stage. The magnetic characteristics of the composite provide the possibility of effective magnetic separation of the material after sorption.
