In this experiment, the dissolution concentration of metal ions, SEM, TEM, and XRD were used as the stability evaluation index of the catalyst, and the activity and stability of the catalyst were further comprehensively evaluated. The catalyst Pd-catalyst was used to treat simulated printing and dyeing waste-water by CWAO method. The results shows that the morphology and structure of the Cu-Fe-Pd-La/γ-A1 2 O 3 (ratio 1:1:1:3) catalyst do not change significantly before and after the CWAO reaction, indicating that the experimentally prepared Pd-catalyst has better stability.
