Research on the Preparation of Catalyst in Dealing with AR88 by CWAO

Abstract:

This article describes the research on the preparation of the catalyst which is used to deal with Acid Red 88 by catalytic wet oxidation. The experiment investigated the effect of catalyst carrier, impregnation and roast temperature etc on the catalytic activity. Found the optimal conditions to make catalyst finally, it can be described as follows: take lithium silicon powder as a carrier; 0.1mol /L iron nitrate as active ingredients to dip 20 hours; and then, calcined 90 minutes under the condition of 500°C. The removal rate of Acid Red 88 can reach up to 97.2% by the use of these catalysts after 60 minutes reaction.
