Summary: The study developed a H2O2-free photo-Fenton process using BiVO4 as a semiconductor and Fe3+ as an additive to effectively degrade antibiotics. Comparisons between H2O2-free photo-Fenton and photocatalytic reactions showed the former had higher degradation rates under optimized conditions. The study deepened the understanding of mechanism and kinetics between photo-Fenton and photocatalytic reactions on the same catalyst, and highlighted the potential of H2O2-free photo-Fenton reactions on other semiconductors in treating wastewater with various antibiotics.

Summary: The combined process of solar Photo-Fenton treatment and bacterial degradation using Ochrobactrum sp. CPD-03 has been found effective in degrading Chlorpyrifos (CP) in wastewater. In vivo biotoxicity analysis showed that the use of this combined process reduces the toxic effects of CP on embryonic zebrafish. The study suggests the use of this technique for efficient degradation of CP and reduction of in vivo biotoxicity.

Summary: This study applied Fe-citrate-based photo-Fenton chemistry to degrade CPF and assess its phytotoxicity. Adjusting the initial CPF concentration, time, and Fe-citrate/H2O2 ratio during the photo-Fenton reaction can effectively remove CPF. Furthermore, treating agricultural runoff contaminated with CPF using a raceway pond reactor can reduce phytotoxicity and improve seed germination.

Summary: A novel porphyrin-based metal organic gel (MOG) and magnetic metal organic gel (MMOG) were successfully synthesized. The MMOG showed high photo-Fenton activity in the degradation of Rhodamine B under visible light and could efficiently kill bacteria under visible light. The unique magnetic property of MMOG allowed for easy recovery by an external magnetic field.

Summary: In this study, a green solar photo-Fenton system based on natural pyrite was developed for the efficient degradation of carbamazepine. The system utilized natural organic acids to promote in-situ production of H2O2 and Fe(II) species, ensuring an efficient Fenton reaction without the need for additional H2O2 and pH adjustment. The system demonstrated a significant enhancement in the degradation efficiency of carbamazepine compared to pure pyrite, showcasing the potential of natural pyrite for environmental remediation.

Summary: The aim of this study is to optimize the degradation of two pharmaceutical pollutants, amoxicillin and acetaminophen, in water by solar photo-Fenton process. The use of ethylenediamine-N,N’-disuccinic acid (EDDS) as a complexing agent was found to be effective in maintaining iron in solution at neutral pH. The results showed that the highest initial degradation rates of the target compounds were achieved by using 3 mg/L of Fe(III), an Fe-EDDS ratio of 1:2, and 2.75 mg/L of H2O2. The experimental design was successfully validated using real wastewater samples spiked with the target compounds.

Summary: The Syrian natural magnetite was used in a photoFenton reaction to remove methylene blue from aqueous solutions. Kinetic and thermodynamic parameters were evaluated, with the pseudo-first-order model being more suitable for describing the degradation process. The activation energy values indicated a low energy barrier for the degradation reaction, and thermodynamic parameters suggested the process was endothermic and spontaneous.

Summary: Excessive discharge of wastewater containing isothiazolinone bacteriostatic agent poses serious threats to human health and environmental safety. A NH2-MIL-53(Fe)-based adsorptive photo-Fenton-like system was constructed for efficiently adsorbing and photodegrading 1,2-benzisothiazolin-3-one (BIT) under solar light. The system achieved more than 90% removal of BIT using NH2-MIL-53(Fe) in the presence of H2O2 under solar light irradiation.
