In this study, the antibiotic sulfamethoxazole (SMX) removal was investigated and optimized using electrocoagulation process (ECP). The effective parameters including initial SMX concentration, current density, solution pH, reaction time, type concentration of supporting electrolytes, types electrodes (Fe/Fe, Al/Al, Cu/Cu, Zn/Zn), on treatment were investigated. Response surface methodology (RSM) applied for designing study based central composite design (CCD). maximum efficiency energy consumption 99.9% 0.743 kWh m-3, respectively, found in optimum condition 20 mg L-1, density 15.0 mA cm-2, pH 9.0, time 17.0 min, mM NaCl as electrolyte Fe/Fe electrode. statistical data p-value < 0.0001, F-value 311.2, high determination coefficient (R2) 0.9878, adjusted R2 0.9847, predicted 0.9753 revealed satisfactory correlation between values experimental findings developed model. ECP involves a combination multiple mechanisms such coagulation, flocculation, flotation, sedimentation, adsorption that act synergistically to remove contaminants by applying electrical current.
