Diclofenac was chosen as an targeted pollutant, because, it was a commonly used nonsteroidal anti-inflammatory drug, with being detected in various water bodies.
In our previous study, DCF was widely detected in secondary effluents of china WWTPs, and posed high risks (RQ>1) to aquatic organisms.
Persulfate-based AOPs emerge as a cutting-edge purification technology due to their high efficiency in degradation and mineralization of organic contaminants. Persulfates activation by carbon-based catalysts is an effective process to remove PPCPs with various forms.
The micro-structure and the intrinsic structural complexity of carbon materials can result in the difference in catalytic mechanism during the activation of PS.
Hence, Classifying the relationship between the ROS formed from PS and catalytic sites of carbon materials is necessary and helpful to design efficient and expectable PS oxidation process. |
