Silicon-based adsorbent and its application in municipal solid waste incineration flue gas treatment

Abstract

The present invention discloses a silicon-based adsorbent and its application in the treatment of municipal solid waste incineration flue gas. The silicon-based adsorbent employs polymer-modified composite clay as a matrix, with humic acid loaded on the surface; wherein the composite clay is a combination of palygorskite, chlorite, and illite. The silicon-based adsorbent of the present invention exhibits excellent adsorption performance for dioxins, maintains good mechanical stability under both alkaline and neutral conditions, effectively overcomes the problem of humic acid readily dissolving in such environments, broadens the application scope of the adsorbent, and significantly improves the adsorption efficiency for dioxins. 20 25 25 60 97 21 O ct 2 02 5 A B S T R A C T 2 0 2 5 2 5 6 0 9 7 2 1 O c t 2 0 2 5
