The kinetic and pathway of meta-cresol (m-cresol) degradation were studied by persulfate oxidation through UV/ozone activation (UV/O₃–Na₂S₂O₈) to improve m-cresol removal to eliminate ecological risks. Experimental results showed that the degradation effect of m-cresol with an initial concentration of 50 mg/L was 99.8% in 30 min under the optimization conditions. The reaction kinetic model in the UV/O₃–Na₂S₂O₈ system shows that the initial pH value, the respective ozone, and the persulfate dosage were positively correlated with the degradation rate constant value (k). The apparent degradation rate of m-cresol in the UV/O₃–Na₂S₂O₈ system was 0.2216 min⁻¹, and the synergy factor (f) was larger than 1, thereby demonstrating a synergistic effect of UV, ozone, and persulfate. The dominant free radicals in the system were sulfate radical (SO- 4·) and hydroxyl radical (·OH), and the contribution ratio of SO- 4· to m-cresol degradation was higher than ·OH. The degradation process of m-cresol by UV/O₃ − Na₂S₂O₈ was mainly through the electrophilic addition reaction to substitute the ortho- and para-positions of the hydroxyl group on the benzene ring, followed by the ring-opening reaction and mineralization of the aliphatic compound to achieve the complete degradation of m-cresol.

通过过硫酸盐通过紫外线/臭氧活化（UV / O ₃ -Na ₂ S ₂ O ₈）的过硫酸盐氧化来研究间甲酚（间甲酚）降解的动力学和途径，以改善间甲酚的去除，从而消除生态风险。实验结果表明，在优化条件下，初始浓度为50 mg / L的间甲酚在30 min内的降解率为99.8％。在UV / O ₃ -Na ₂ S ₂ O ₈系统中的反应动力学模型表明，初始pH值，相应的臭氧和过硫酸盐剂量与降解速率常数值正相关（k）。在UV / O ₃ -Na ₂ S ₂ O ₈系统中间甲酚的表观降解速率为0.2216 min ^-1，并且协同因子（f）大于1，从而证明了UV，臭氧，和过硫酸盐。系统中的主要自由基为硫酸根（SO-4·）和羟基（·OH），SO-4·对间甲酚降解的贡献率高于·OH。UV / O ₃  -Na ₂ S ₂ O ₈对间甲酚的降解过程 主要是通过亲电加成反应取代苯环上羟基的邻位和对位，然后进行开环反应和脂肪族化合物的矿化，以实现间甲酚的完全降解。
