煤气化细渣负载CoO活化PMS高效降解双酚A
Coal gasification fine slag supported CoO catalyst for the efficient degradation of bisphenol A by activating peroxymonosulfate process
摘要
Abstract
The resource application of coal gasification fine slag is an important way to achieve the"carbon peaking and carbon neutrality"in China.In this study,the coal gasification fine slag(FS)obtained from Space Furnace was used as the catalyst carrier after simple water washing and ultrasonic impregnation to prepare CoO@FSC with well dispersion.The as-prepared catalyst was used to activate peroxide single sulfate(PMS)for the efficient degradation of wastewater containing bisphenol A(BPA).The results showed that the CoO particles were uniformly distributed on the surface of the fine slag,which avoided the accumulation of metal oxides in the actual catalytic degradation process and thus provided more active sites for activating PMS.BPA could be completely degraded within 25 minutes by CoO@FSC under the conditions of 30℃ ,0.2g/L catalyst dosage,6mmol/L PMS dosage and 50mg/L BPA concentration and the degradation could be effective a wide pH range from weak acid to alkaline substrate.The free radical quenching experiment confirmed that the main active substances in the BPA catalytic degradation process were 1O2 and·O-2.The good catalytic performance of CoO@FSC demonstrated the potential application of coal gasification fine slag in the degradation of organic pollutants,and provided a theoretical basis for its further utilization.关键词
