Summary: In this research, a bench-scale installation was tested for the heterogeneous electro-Fenton treatment of clofibric acid. The use of a pressurized-jet aerator and iron-containing alginate beads as catalysts showed promising results in enhancing the efficiency of pollutant removal and reducing energy consumption. However, further increase in pressure did not lead to significant improvement. The integrity of the catalyst was not compromised by pressure. A mathematical model was also developed to better understand the behavior of the reaction system.

Summary: Three CuFe-MOFs with different structures were synthesized successfully by varying the ratio of solvents, salts, or temperature. CuFe(BDC-NH2)(D) and CuFe(BDC-NH2)(S) exhibited improved PMS activation for Rhodamine B removal, achieving a removal rate of around 92%. The best degradation system for a mixture of antibiotic and anti-inflammatory drugs was the photo-assisted activation of PMS using CuFe(BDC-NH2)(D) and CuFe(BDC-NH2)(S), resulting in complete degradation within 1 hour. CuFe(BDC-NH2)(R)/PMS showed higher antibacterial activity due to its higher copper content.
