摘要: Disclosed are a catalytic oxidation catalyst, a preparation method therefor, and a method for the deep treatment of organic matters in an MDI saline. The catalyst comprises a carrier and an active component, wherein the carrier is titanium dioxide, and the active component is an organic neutral ligand-metal complex type ionic liquid. The deep treatment method comprises: (1) adjusting the pH value of the MDI saline, and adding an oxidizing agent for treatment; and (2) bringing the MDI saline having been treated in step (1) into contact with the catalytic oxidation catalyst for a catalytic oxidation reaction to obtain a deeply treated saline. The catalyst can reduce or even avoid the loss of a metal from the catalyst while ensuring that the catalytic oxidation effect is improved. The deep treatment method is simple and readily practicable, has a high treatment efficiency, and does not produce secondary pollution.
