The initial screening showed that Fe(III)\u2010EGTA and Fe(III)\u2010DTPA could significantly improve the rate of sulfamethazine removal. The optimum molar ratios of persulfate to Fe(III)\u2010DTPA and Fe(III)\u2010EGTA were 100:1 and 100:2.5. The predicted percentage of sulfamethazine removal under the optimized conditions, obtained using response surface methodology, was ~99% for both catalysts. The pH range of 6 to 8 did not significantly affect the performance of UV\/PS in the removal of sulfamethazine. The percentage sulfamethazine removal in the selected water samples was ranged from 93.6% to 99.6%, agreeing with the predicted value. The performance of both catalysts in activating UV\/PS is comparable with that of the frequently used Fe(III)\u2010EDDS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Practitioners
