Degradation of sulfamonomethoxine by iron–copper catalyst-activated persulfate

Sulfamonomethoxine (SMM) is an emerging organic pollutant that is environmentally persistent, highly toxic, and difficult to degrade, and there is an urgent need to develop efficient degradation methods. Therefore, this paper investigates the degradation of SMM using iron–copper catalyst-activated persulfate (PS). With an iron–copper catalyst amount of 1.5 g/L, initial sodium persulfate solution concentration of 2 mmol L−1, and initial solution pH = 7, the SMM removal rate reached approximately 99.7
