Abstract

This study assessed the efficacy of ZrO2-based catalysts with different Mn(II) and Co(II) metal loadings for catalytic degradation of ibuprofen using peroxymonosulfate anion as oxidant. The support was prepared via co-precipitation, and metal ion deposition was achieved through incipient wetness impregnation. Catalysts were characterized by atomic absorption spectrometry, X-ray diffraction, Fourier-Transform infrared spectroscopy, and scanning electronic microscopy. Optimal experimental conditions resulted in complete ibuprofen degradation in 30 min, with 63.3% mineralization. The best-performing catalyst was reusable up to three times. Both sulfate and hydroxyl radicals were generated in the oxidant activation process.

用氧化锆支撑的锰和钴催化剂高效活化过一硫酸盐以氧化布洛芬
本研究评估了不同锰(II)和钴(II)金属负载的 ZrO2 基催化剂以过氧单硫酸根阴离子为氧化剂催化降解布洛芬的功效。支撑物通过共沉淀法制备,金属离子沉积通过初湿浸渍法实现。通过原子吸收光谱、X 射线衍射、傅立叶变换红外光谱和扫描电子显微镜对催化剂进行了表征。最佳实验条件可使布洛芬在 30 分钟内完全降解,矿化度达 63.3%。性能最好的催化剂可重复使用三次。在氧化剂活化过程中会产生硫酸根和羟基自由基。
