Example Embodiment
[0039] Example 1
[0040] (1) Prepare 55 mg / L sulfamethoxazole solution at room temperature, take 50 mL of the solution in a 100 mL conical flask, add 5 mg (Mn:Co=1:20) hollow cobalt-rich bimetallic sulfide, and stir well.
[0041] (2) Add 25mg KHSO to the reaction system 5 , Sampling at intervals, quenching with methanol, and measuring the residual sulfamethoxazole concentration using an instrument. See the results of the experiment figure 1 . Where C 0 Is the initial concentration, C is the final concentration, C / C 0 Indicates degradation rate. Same below.
