description Real hospital wastewater was effectively treated by a promising technology based on degradation reaction catalyzed by Fe0 under microwave irradiation in this work. Fe0 powders were synthesized and characterized by different techniques, resulting in a single-phase sample with spherical particles. Optimum experimental conditions were determined by a central composite rotatable design combined with a response surface methodology, resulting in 96.8% of chemical oxygen demand reduction and 100% organic carbon removal, after applying MW power of 780 W and Fe0 dosage of 0.36 g L−1 for 60 min. Amongst the several organic compounds identified in the wastewater sample, diclofenac and ibuprofen were present in higher concentrations; therefore, they were set as target pollutants. Both compounds were completely degraded in 35 min of reaction time. Their plausible degradation pathways were investigated and proposed. Overall, the method developed in this work effectively removed high concentrations of pharmaceuticals in hospital wastewater

Fe0 powders were synthesized and characterized by different techniques, resulting in a single-phase sample with spherical particles. Optimum experimental conditions were determined by a central composite rotatable design combined with a response surface methodology, resulting in 96.8% of chemical oxygen demand reduction and 100% organic carbon removal, after applying MW power of 780 W and Fe0 dosage of 0.36 g L−1 for 60 min. Amongst the several organic compounds identified in the wastewater sample, diclofenac and ibuprofen were present in higher concentrations; therefore, they were set as target pollutants. Both compounds were completely degraded in 35 min of reaction time. Their plausible degradation pathways were investigated and proposed. Overall, the method developed in this work effectively removed high concentrations of pharmaceuticals in hospital wastewaterEn este trabajo, las aguas residuales hospitalarias reales fueron tratadas eficazmente mediante una tecnología prometedora basada en la reacción de degradación catalizada por Fe0 bajo irradiación de microondas. Los polvos de Fe0 se sintetizaron y caracterizaron mediante diferentes técnicas, dando como resultado una muestra monofásica con partículas esféricas. Las condiciones experimentales óptimas se determinaron mediante un diseño central compuesto giratorio combinado con una metodología de superficie de respuesta, lo que resultó en una reducción del 96,8% de la demanda química de oxígeno y una eliminación del 100% de carbono orgánico, después de aplicar una potencia de MW de 780 W y una dosis de Fe0 de 0,36 g L − 1. durante 60 min. Entre los varios compuestos orgánicos identificados en la muestra de aguas residuales, el diclofenaco y el ibuprofeno estaban presentes en concentraciones más altas; por lo tanto, se establecieron como contaminantes objetivo. Ambos compuestos se degradaron completamente en 35 min de tiempo de reacción. Se investigaron y propusieron sus posibles vías de degradación. En general, el método desarrollado en este trabajo eliminó de manera efectiva las altas concentraciones de productos farmacéuticos en las aguas residuales de los hospitales.Vieira, Yasmin-will be generated-orcid-0000-0003-4053-4042-600A.
