Abstract

The invention discloses a nano-composite material used for water purification, which includes, by weight, 48-54 parts of chitosan, 12-16 parts of nano-TiO2, 24-28 parts of active carbon supported nano-bentonite and 3-6 parts of nano-hydrotalcite, wherein the mass ratio of the chitosan, the nano-TiO2, the active carbon supported nano-bentonite to the nano-hydrotalcite is (65-75):(8-12):(14-18):4. With chitosan being a carrier, the product has stable properties. The cross-linked structure in the active carbon form fine pores, so that the product has well-developed pore structure; by supporting the nano-bentonite on the active carbon, the nano-bentonite is increased in specific surface area, so that the product is enhanced in heavy metal adsorption effect.

Description

technical field [0001] The invention relates to the technical field of nano functional materials, in particular to a nano composite material used for water body purification and a preparation method thereof. Background technique [0002] Nanomaterials refer to the general term for materials composed of nanoparticles with a size less than 100nm. Since nanoparticles are in the transition zone between atomic clusters and macroscopic objects, they have surface effects, small size effects and macroscopic two-word tunnel effects, so nanomaterials have special properties. Based on the optical, electrical, magnetic, and mechanical properties of ordinary materials, nanomaterials can be divided into five categories according to their physical form: nanoparticles, nanofibers, nanomembranes, nanoblocks, and nanophase separation fluids. Industrial wastewater refers to process The waste water and waste liquid discharged during the production process, which contains industrial production m...
