Abstract

See full text

The invention discloses a humic acid type adsorption material as well as a preparation method and application thereof. The humic acid type adsorption material is prepared by taking carboxymethyl cellulose or salts thereof, humate and montmorillonite as raw materials and adding a monomer, a cross-linking agent and an initiator through aqueous solution polymerization. The synthesized porous material is great in specific surface area, can quickly get close to water molecules in water to form hydrogen bonds, and finally achieves the purpose of removing organic dye pollutants through electrostatic attraction effect with dye molecules. The humic acid type adsorption material is low in raw material price, is simple in synthesis process, and is green and environmentally friendly.
