Photocatalytic Degradation of Selected Non-Opioid Analgesics Driven by Solar Light Exposure

Year: 2024

Type: article

Abstract: The residues of pharmaceutical compounds are often resistant to degradation, causing an environmental problem. Our research aimed to perform a study of the photocatalytic and photoelectrocatalytic degradation of non-opioid analgesic paracetamol and some of the non-steroidal anti-inflammatory drugs (NSAIDs) (ketoprofen, naproxen, diclofenac, and ibuprofen). Semiconductor WO3, Fe2O3, and WO3/Fe2O3 photocatalysis using solar energy lamps were applied for this purpose. As a result of the photocatalytic processes, high decomposition efficiency was obtained for ketoprofen (97%) and naproxen (70%). Low photodegradation yields were achieved for diclofenac. Under the used measurement conditions, both paracetamol and ibuprofen were not degraded.
