摘　　要：以萘系染料中间体中具有代表性的H-酸(1-氨基-8-萘酚-3,6-二磺酸,分子式为C10H9O7S2N)的水溶液为研究对象,分别采用以等体积浸渍法制备的不同负载量的Cu-Zn/ZSM-5催化剂、以共沉淀法制得的Cu-Zn-Al催化剂对H-酸水溶液进行湿空气催化氧化降解。研究结果表明:对于处理H-酸水溶液,Cu-Zn/ZSM-5系列催化剂的COD去除率更高,这主要是由于催化活性中心在分子筛上获得了更优的分散性;最佳的CuO负载量为3.41%,ZnO负载量为1.16%,此时H-酸COD去除率为88.18%。H-acid （C10H0O7S2N） solution, one of typical dye intermediates of naphthalene derivatives, was degraded respectively by Cu-Zn/ZSM-5 catalysts prepared by impregnation method using ZSM-5 zeolite as substrate, and Cu-Zn-Al catalyst prepared by co-preoipitation method during catalytic wet air oxidation. Cu-Zn/ZSM-5 catalysts present higher COD removal rate of H-acid solution compared with Cu-Zn-Al catalyst, which indicates that the active components are dispersed more uniformly on Cu-Zn/ZSM-5 catalysts than on the catalyst prepared by co-preclpitation. The optimal loading amount of CuO and ZnO are 3.41% and 1, 16% respectively, and the COD removal rate of the H-acid is 88.18%.
