Abstract
Abstract Sulfamethoxazole, one of the most frequently used sulfonamide antibiotics, has been frequently detected in the aquatic environment. The long-term presence of sulfamethoxazole in natural water bodies can easily lead to the development of resistant bacteria, posing a serious threat to the health and safety of aquatic organisms and humans. In this paper, the degradation of sulfamethoxazole by a combined system of ultrasound/PW12/KI/H2O2 was investigated based on advanced oxidation techniques. The effects of different factors, such as ultrasonic power, initial pH, KI concentration, H2O2 concentration, PW12 concentration and initial concentration of sulfamethoxazole, on the degradation effect were discussed. The reactive radicals in the system, the degradation products of sulfamethoxazole and the main degradation pathways were analyzed. The results indicate that the US/PW12/KI/H2O2 system is of great potential application value in removal of organic pollution and environmental purification.
