The relevant results were published in Journal of Colloid and Interface Science. Sulfadiazine (SDZ), a kind of synthetic sulfadiazine antibiotic, is widely used in clinical and animal husbandry industries. However, due to its large-scale use and unqualified discharge of wastewater, more and more antibiotic residues are detected in the water environment. These antibiotics are still highly toxic at very low concentrations. Due to the stable chemical structure of sulfadiazine, it is difficult to solve the residual problem with conventional processing technology.
