Powder activated carbon/Fe3O4 hybrid composite as a highly efficient heterogeneous catalyst for Fenton oxidation of tetracycline: degradation mechanism and kinetic

In this work, we prepared and used a composite of powder activate carbon/Fe₃O₄ magnetic nanoparticles (PAC/Fe₃O₄ MNPs) as a heterogeneous catalyst to remove tetracycline (TC) from aqueous solution.
