Abstract

The application discloses a carbon nanotube-montmorillonite composite adsorption material suitable for soil remediation and a preparation method thereof. The carbon nanotube-montmorillonite hybrid material is obtained by growing carbon nanotubes on the surface of nickel-containing montmorillonite with waste polyolefin as a carbon source, then the carbon nanotube-montmorillonite hybrid material is carboxylated and aminated, and finally the target product is obtained by modifying the carbon nanotube-montmorillonite hybrid material with methyl methacrylate and the like grafting products. The composite adsorption material provided by the application can effectively adsorb heavy metal ions in the surrounding environment, and is derived from waste polyolefin, thereby helping to reduce white pollution.
