Catalytic ozonation for the degradation of p-chlorobenzoic acid in aqueous solution by Ni supported activated carbon

摘要：

Catalytic ozonation of p-chlorobenzoic acid (p-CBA) in aqueous solution has been carried out where transitional metal (Ni, Cu, Mn, Co, Fe) supported activated carbon was used as catalysts. Ni supported activated carbon (Ni/AC) catalyst, which is prepared by the dipping method with an aqueous solution of Ni(NO3)2, shows higher catalytic activity. Activated carbon and Ni/AC catalyst were characterized by XRD, SEM and BET. The presence of either activated carbon or Ni/AC catalyst significantly improves the degradation of p-CBA and TOC removal compared to ozonation alone. Moreover, the Ni/AC catalyst still shows well catalytic activity and stability during p-CBA ozonation after six repetitive uses.
