Process for degrading ionic liquid based on ultraviolet light activated persulfate

The invention discloses a process for degrading ionic liquid based on ultraviolet light activated persulfate, and relates to the technical field of ionic liquid degradation. The degradation effect is improved; comprising the following steps: preparing 250mL of ionic liquid with the initial concentration of 200mg/L; the prepared ionic liquid is added into a glass reactor for a reaction, the glass reactor is of a conical structure, the volume of the glass reactor is 300 ml, the reaction temperature ranges from 25 DEG C to 27 DEG C, and the pH in the glass reactor is kept at 6-7. According to the present invention, the persulfate is provided, such that the persulfate has advantages of high oxidation capacity, fast reaction speed, non-toxic degradation by-product and the like, such that the persulfate is more and more favored in pollution treatment, and the sodium persulfate is added into the ionic liquid and is irradiated by using the ultraviolet lamp to achieve the degradation; therefore, the degradation rate o
