A complex precipitation method was adopted to synthesize CuO nanoparticles, and its morphology and structure were characterized. Then, the CuO nanoparticles were taken as the activator in the degradation of ofloxacin with persulfate. Based on the advanced technology of activated persulfate oxidation, the influences of different parameters, including concentration of K2S2O8 and an initial pH of the ofloxacin solution, on the degradation activity of ofloxacin in the wastewater were investigated. It is found that the degradation rate can reach 95.6% with 10 mg/L of ofloxacin in the wastewater with an initial pH of 3.5, by adding 0.003 0 g/L CuO and 1.0 mmol/L K2S2O8. The experiments on capturing free radicals show that SO4-· and O2-· are active species for the catalytic degradation of ofloxacin, which is possibly the catalytic reaction mechanism.

采用络合沉淀法制备了纳米CuO,并对其结构和形貌进行了表征。将纳米CuO作为过硫酸盐降解氧氟沙星的活化剂,基于活化过硫酸盐高级氧化技术,考察了K2S2O8浓度、水体初始pH值等参数对废水中氧氟沙星降解性能的影响。结果表明,在废水中氧氟沙星浓度10 mg/L、CuO投加量0.003 0 g/L、K2S2O8投加量1.0 mmol/L、废水初始pH=3.5条件下,氧氟沙星降解率为95.6%。自由基捕获实验结果表明,自由基SO4-·和O2-·是实现氧氟沙星催化降解的活性物种,并给出了可能的催化反应机理。

采用络合沉淀法制备了纳米CuO,并对其结构和形貌进行了表征。将纳米CuO作为过硫酸盐降解氧氟沙星的活化剂,基于活化过硫酸盐高级氧化技术,考察了K2S2O8浓度、水体初始pH值等参数对废水中氧氟沙星降解性能的影响。结果表明,在废水中氧氟沙星浓度10 mg/L、CuO投加量0.003 0 g/L、K2S2O8投加量1.0 mmol/L、废水初始pH=3.5条件下,氧氟沙星降解率为95.6%。自由基捕获实验结果表明,自由基SO4-·和O2-·是实现氧氟沙星催化降解的活性物种,并给出了可能的催化反应机理。

A complex precipitation method was adopted to synthesize CuO nanoparticles, and its morphology and structure were characterized. Then, the CuO nanoparticles were taken as the activator in the degradation of ofloxacin with persulfate. Based on the advanced technology of activated persulfate oxidation, the influences of different parameters, including concentration of K2S2O8 and an initial pH of the ofloxacin solution, on the degradation activity of ofloxacin in the wastewater were investigated. It is found that the degradation rate can reach 95.6% with 10 mg/L of ofloxacin in the wastewater with an initial pH of 3.5, by adding 0.003 0 g/L CuO and 1.0 mmol/L K2S2O8. The experiments on capturing free radicals show that SO4-· and O2-· are active species for the catalytic degradation of ofloxacin, which is possibly the catalytic reaction mechanism.
