Non-radical-based advanced oxidation processes, particularly those dominated by high-valent metals, have caught a great deal of attention because their exceptional degradation selectivity and robust interference resistance. This study reports the synthesis novel ferrite, designated as Co0.5Ni0.5Fe2O4, through solvothermal reaction, aimed at activating PMS for removal TCH from water. It was observed that calcination time played an important role in adjusting particle size catalyst, which subsequently increased its surface area. enlargement, turn, led to increase active sites, ultimately enhancing catalytic efficiency. Within Co0.5Ni0.5Fe2O4/PMS system, metals Fe(IV) Co(IV) became prominent primary species, with O21 serving secondary contributor. The activation mechanism thoroughly analyzed discussed. Co0.5Ni0.5Fe2O4 exhibited remarkable stability complex reaction environments during multiple recycling tests, maintaining efficiency exceeding 98%. not only increases awareness interaction between catalyst structure performance but also provides viable platform metal-dominated ferrite catalysts.
