- Abstract:
- A copper hydroxyphosphate catalyst was prepared by hydrothermal method, and the catalytic degradation of p-nitrophenol with copper hydroxyphosphate as a catalyst was studied in the presence of hydrogen peroxide. The effects of catalyst dosage, hydrogen peroxide dosage, pH value, temperature, initial concentration and other conditions on the degradation process were tested. The results show that copper hydroxyphosphate has excellent catalytic degradation of p-nitrophenol, and the degradation rate of p-nitrophenol can be greatly accelerated by adding a small amount of copper hydroxyphosphate catalyst. The larger the amount of catalyst, the larger the amount of hydrogen peroxide, and the faster the degradation rate; If the pH value is increased, the degradation rate will be slower, and the optimized pH is 2~3; Increasing temperature can speed up the rate of degradation.
