Emerging contaminants pose a serious hazard to the water environment and human health due to their difficult degradation. In recent years, periodate-based oxidation processes have aroused tremendous attention in environment remediation due to their high oxidative potential for the degradation of contaminants and fair stability in the water. Periodate activation methods (i.e., thermal activation, photoactivation, microwave and ultrasonic activation, metal catalyst activation, carbon activation, H
