Dexamethasone (DXM) was the first drug used to treat COVID-19, only a small part is metabolized and has been identified in wastewater surface water, conventional treatments do not remove these compounds, therefore new technologies must be developed. A commercially injectable solution containing dexamethasone removed by heterogeneous sono/photo-Fenton (SPF) process using clinoptilolite zeolite (CZ) modified with Fe (CZ-Fe) an electrodeposition method. The effect of initial concentration (1.2, 3, 5.5, 8, 9.7 mg/L), H2O2 dose (9.8, 15, 22.5, 30, 35.1 mg/L) hydraulic retention time (HRT, 39.5, 60, 90, 120, 140 min) were evaluated through central composite design (CCD). frequency ultrasound kHz. optimal conditions 5.5 mg/L DXM, 22.5 min obtaining 85.4% DXM UV-Vis, 99% high-performance liquid chromatography (HPLC) 76% chemical oxygen demand (COD) removal. systems generated 12, 25, 40.5 45.5 total oxidant at 20, 100 kHz, respectively. In individual effects, UV radiation 23.6%, 18.1% 14% DXM. kinetic studies, best fit obtained for Behnajady-Modirshahla-Ghanbery (BMG) model. SPF improved mass transfer within reaction media, oxidation rate consumption H2O2, no sludge generated. Finally, another formed during (H•, HO2•, O2-•) contributed
