FeO(x)-MoO(3)-P(2)O(5) (x=1 or 1.5) composite catalyst was prepared by solid reaction method and characterized by X-ray diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS). Its catalytic activities on degradation of a heteropolyaromatic dye, methylene blue (MB), were also investigated under mild condition. In order to determine the optimum operating condition, the orthogonal experiments were devised. And the results revealed that initial concentration of MB was the key factor that affected the decoloration, while the catalysts dose has an insignificant effect. Environmental estimation was also done and the results showed that the treated wastewater have little influence on plant growth and could totally be applied to irrigation.
采用固相反应法制备了FeO(x)-MoO(3)-P(2)O(5)（x = 1或1.5）复合催化剂，并用X射线衍射（XRD）和X射线光电子能谱（XPS）对其进行了表征。在温和条件下，还研究了该催化剂对杂多芳族染料亚甲基蓝（MB）的降解活性。为了确定最佳操作条件，设计了正交实验。结果表明，MB的初始浓度是影响脱色的关键因素，而催化剂用量的影响不显著。还进行了环境评估，结果表明处理后的废水对植物生长影响很小，可完全用于灌溉。
