    Evaluation of Nanomagnetite–Biochar Composite for BTA Removal by Carolina Guida, Nathaniel Findling, Valérie Magnin, Fabienne Favre Boivin, Laurent Charlet

    Published 2025-01-01
    “…Within the short time scale (up to 8 h), the removal of BTA by nanomagnetite–biochar composite was shown to be due to BTA deprotonation by the nanomagnetite surface. Through proton liberation, Fe²⁺ is released in accordance with the reaction Fe₃O₄ + 2H⁺ → Fe₂O₃ + Fe²⁺ + H₂O, which likely influences BTA complexation and its possible redox degradation. …”
