Nanocomposite water purification material based on porous material and preparation method of nanocomposite water purification material

Abstract

The invention discloses a nanocomposite water purification material based on a porous material and a preparation method of the nanocomposite water purification material. The nanocomposite water purification material is prepared from nano titanium dioxide powder and nanoporous carbon, wherein the nano titanium dioxide powder is of a porous structure, the specific surface area is 410.2-476.8 m<2> / g,the pore volume is 0.314-0.35 cm<3> / g, and the minimum pore diameter is 2.54-3.49 nm; the preparation method comprises the steps: in parts by weight, 10 parts of the nano titanium dioxide powder and20 parts of the nanoporous carbon are weighed to be stirred and mixed for 3-5 min; and the mixture is mechanically ground for 5-10 min, and the porous powdery nanocomposite water purification materialis obtained. Compared with the prior art, the nanocomposite water purification material has the following advantages that components are not complex and comprise the nano titanium dioxide powder andthe nanoporous carbon, the adsorption property to heavy metal such as arsenic and organic micropollutants is excellent, the nano titanium dioxide powder is prepared to be of the porous structure, thespecific surface area is increased, and the adsorption effect is improved.
