We developed a novel and efficient degradation process for oxytetracycline (OTC), an antibiotic that remains in the aquatic environment and affects humans and animals. OTC was decomposed by applying a fusion TiO₂ photocatalytic oxidation process adding microwaves, and various unit technologies and their fusion effects were investigated. As the microwave power increased, the decomposition efficiency increased, and the highest decomposition rate was shown in the neutral pH reaction solution. The decomposition rate was greatly increased by the addition of hydrogen peroxide, and it showed a synergistic effect that the decomposition efficiency was doubled by fusion with other processes. Eleven intermediate products of OCT decomposition were detected by liquid chromatography0mass spectrometry; CO₂, H₂O, NH ⁺₄ , and NO ⁻₃ by active oxidizing species, such as OH radicals generated by the microwave-assisted fused TiO₂ photocatalytic oxidation process were mineralized.

我们开发了一种新型有效的土霉素 (OTC) 降解工艺，土霉素是一种残留在水生环境中并影响人类和动物的抗生素。采用加微波的熔融TiO ₂光催化氧化工艺分解OTC，研究了各种单元技术及其熔融效果。随着微波功率的增加，分解效率提高，在中性pH反应溶液中分解率最高。过氧化氢的加入大大提高了分解率，与其他工艺融合后，分解效率提高了一倍，呈现出协同效应。液相色谱-质谱检测了11个OCT分解的中间产物；二氧化碳₂、H ₂ O、NH ⁺ ₄和 NO ^- ₃通过活性氧化物质，如微波辅助熔融 TiO ₂光催化氧化过程产生的 OH 自由基被矿化。
