Photocatalytic Degradation of Pharmaceutical Amisulpride Using g-C3N4 Catalyst and UV-A Irradiation

In the present study, photocatalytic degradation of amisulpride using g-C3N4 catalyst under UV-A irradiation was investigated. The process evaluated in terms its effectiveness to remove from ultrapure and real municipal wastewater. High removal percentages were achieved both aqueous matrices. However, a slower rate observed wastewater as matrix that could be attributed complex chemical composition. transformation products (TPs) identified with liquid chromatography–mass spectrometry (LC–MS) Based on TPs, pathways are proposed which include mainly oxidation, dealkylation, cleavage methoxy group. Moreover, contribution reactive species mechanism studied well-documented scavengers, significant role h+ O2•− reaction proved. evolution ecotoxicity also estimated microalgae Chlorococcum sp. Dunaliella tertiolecta. Low toxicity during overall without formation toxic TPs when water used matrix. case wastewater, an increased at beginning is composition application heterogeneous photocatalysis reduced toxicity, almost complete detoxification end process. Our results accordance literature data reported effective for
