The degradation of sulfadiazine (4-amino-N-pyrimidin-2yl-benzenesulfonamide, SDZ), a widely used sulfonamide antibiotic, in aqueous solution under electron beam irradiation was investigated to explore its potential as an Advanced Oxidation Process for environmental remediation. This study evaluated the effects dose, initial concentration, and pH on efficiency. It found at 0.5 kGy that efficiency decreased with increasing SDZ from 83.0% 5 mg/L 35.0% 30 mg/L. kinetic results showed pseudo-first order model. efficiencies reached 80.8%, 75.3%, 69.5% 69.8%, respectively, 3.0, 6.3, 9.0, 11.0 3.0 kGy, indicating dependence beam. maximum removal around 90% after UV analysis 99% HPLC 10mg/L absorbed doses 2–3 6.3.
