 Example 1
 First adjust the pH value of the dye wastewater with HCl or NaOH to make 1≤pH≤12, then add 10mL of 50-150mg / L anthraquinone dye AB80 aqueous solution into a 25mL glass test tube, then add the catalyst to the system, and blow 15mL at one time Air, seal, and put it into an intelligent light incubator for light degradation. The light intensity is 5320-5520 Lux, and the light time is 1-30 days. The removal rate of AB80 after the reaction is shown in Table 1.
