In this study, the removal of benzotriazole (BTA), a pervasive aquatic contaminant widely used for its anti-corrosion, UV-stabilizing, and antioxidant properties, by nanomagnetite, biochar, nanomagnetite–biochar composite is investigated. Nanomagnetite were synthesized under anoxic conditions tested BTA efficiency at neutral pH both oxic different time scales. Within short scale (up to 8 h), was shown be due deprotonation nanomagnetite surface. Through proton liberation, Fe²⁺ released in accordance with reaction Fe₃O₄ + 2H⁺ → Fe₂O₃ H₂O, which likely influences complexation possible redox degradation. On longer scale, biochar achieved higher efficiency: 50% removed within 48 h, formation ternary complex surface Ca2+ ions, or 75% after HCl acid wash followed saturation. As presents significant environmental risks extensive industrial applications, present study offers critical insights into mechanisms composite, highlights potential such materials water treatment applications.
