摘　　要：分别以13X,NaY和漂珠为催化剂载体,以Zn^(2+),Fe^(3+),Pb^(2+),Cd^(2+),Cr^(2+),Ni ^(2+),Mn^(2+),Cu^(2+)等过渡金属离子为不同的活性组分,在不同的灼烧条件下制成催化剂,并将其应用于催化臭氧氧化法降解农业生产用品麦草畏中。实验结果显示,以13X为载体、分别以Fe^(3+)和Mn^(2+)作为活性组分、灼烧条件为600℃时制备的催化剂对麦草畏的降解效果最好。With 13X, NaY and floating beads as the catalyst carrier and Zn2＋ ,Fe3＋ , Pb2＋ , Pb2＋ ,Cd2＋ , Cr2＋ , Ni2＋ , Mn2＋ , Cu2＋ as active components, the authors of this paper have prepared catalysts in different calcination conditions, and applied them to catalytic ozonation to degrade dicamba in agricultural production. The experiments results show th at the degra-dation efficiency of wheat straw is the best when the burning conditions are 600 °C with 13X as the carrier and Fe3＋ and Mn2＋ as active components.
