To address the low removal efficiency of ribavirin and chloroquine phosphate, two common antiviral drugs, in traditional wastewater treatment methods, this invention provides a method for treating ribavirin and chloroquine phosphate in water using ultraviolet photocatalysis. This invention removes ribavirin and chloroquine phosphate by adding a certain amount of TiO2 and KMnO4 to the water under ultraviolet irradiation. Results show that the UV / KMnO4 / TiO2 process can efficiently remove ribavirin and chloroquine phosphate, with a treatment effect far exceeding that of UV alone, UV / KMnO4, or UV / TiO2 methods, indicating a significant synergistic effect. Furthermore, since TiO2 is currently the most common photocatalytic material, and potassium permanganate (KMnO4) is a common oxidant, the UV / KMnO4 / TiO2 method is simple, readily available, and easy to implement, making it widely applicable in engineering practice.
