摘要:

水热法制备了羟基磷酸铜催化剂,并在过氧化氢存在下,研究了用羟基磷酸铜为催化剂催化降解对硝基苯酚.试验了催化剂用量、过氧化氢用量、pH值、温度、初始浓度等条件对降解过程的影响.结果表明,羟基磷酸铜具有优良的催化降解对硝基苯酚的性能,少量加入羟基磷酸铜催化剂即可大大加快对硝基苯酚的降解速度;催化剂用量越大,过氧化氢用量越大,降解速度越快;升高pH值则降解速度变慢,优化的pH是2～3;温度升高可加快降解速度.

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.
