A green solar photo-Fenton process for the degradation of carbamazepine using natural pyrite and organic acid with in-situ generated H2O2

Qian Guo et al.

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.

Solar photo-Fenton oxidation of cytostatic drugs via Fe(III)-EDDS at circumneutral pH in an aqueous environment

Hank Hui-Hsiang Lin et al.

Summary: Cytostatic drugs are commonly found in wastewater effluents due to their poor biodegradability, but the Fe(III)-EDDS complex has shown to efficiently degrade cyclophosphamide and 5-fluorouracil under solar light. The addition of EDDS widens the operational pH range of the solar photo-Fenton process, and a suitable Fe(III):EDDS ratio and initial dissolved oxygen level impact the degradation performance. Rapid degradation of the drugs was achieved within 1.5 minutes in the solar photo-Fenton process, with potential for total mineralization under relatively low Fe(III) concentration and H2O2 dosage.
