Efficient oxidative degradation of organic pollutants in real industrial effluents using a green-synthesized magnetite supported on biochar catalyst.

ABSTRACT: This study investigated the degradation of tetracycline (TCN) antibiotic via catalytic activation of periodate (PI, IO₄ ^-) using a novel composite catalyst composed of green-synthesized magnetite nanoparticles supported on water lettuce-derived biochar (MWLB). Characterization results revealed that the magnetic biochar possessed a porous structure, abundant surface functional groups, and high carbon and iron contents. Compared to conventional oxidants such as persulfate, hydrogen peroxide, and peroxymonosulfate, the PI-activated system demonstrated superior degradation efficiency. Process optimization via response surface methodology identified the optimal conditions as follows: PI concentration of 2.05 mM, TCN concentration of 16.52 mg L^-1, a
