A considerable effort has been made to exploring the oxidation of clofibric acid (CA) in advanced processes (AOPs). However, few studies are available on degradation mechanism and toxicity assessment CA saline pharmaceutical wastewater. Here effect chlorine kinetics by Fe2+/ persulfate (PS) process were studied. Oxidation efficiency, mineralisation, intermediate by-products, reactive oxygen species (ROS) examined. Notably, a high removal efficiency (70.91%) but low mineralisation (20.99%) observed at pH 3.0 during Fe2+/PS system. Furthermore, we found Cl− exerted beneficial impact degradation. degree was relatively minor. Under salinity (100 mM) condition, primary within system SO⋅−4, OH·, Cl2/HClO, Fe(IV). Several undesirable chlorinated by-products formed. reasonable pathway proposed. According ecological structure–activity relationship (ECOSAR) programme, some transformation products exhibited higher levels than itself both acute chronic assessment, especially high-salinity environments. These findings elucidate an increased challenges risk for treatment

The chemical tolerance of ketoenamine covalent organic frameworks (COFs) is excellent; however, the tight crystal structure and low surface area limit their applications in field catalysis. In this work, a porous single-atom iron catalyst (FeSAC) with core-shell high was synthesized by using Schiff base COF nanospheres as core nanosheets growth on surfaces. Surface defects were created sodium cyanoborohydride etching treatment to increase specific area. dye degradation experiments peroxymonosulfate (PMS) catalyzed FeSAC proved that methylene blue can be degraded rate constant 0.125 min
