羟基磷酸铜催化降解对硝基苯酚的研究

Catalytic Degradation of P-nitrophenol with Hydrogen Peroxide over Copper Hydrophosphate

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.

The catalyst of copper hydrophosphate was preparaed hydrothermally.The catalytic degradation of p-nitrophenol with hydrogen peroxide over the catalyst synthesed was investigated.The effects of reaction conditions such as catalyst and hydrogen peroxide dose,solution pH,temperature,initial concentration of p-nirophenol on the degradation were experimented.The results show that the copper hydrophosphate behaves the excellent propertities for the catalytic degradation of p-nirophenol.The addtion of small amount...
