Abstract

The invention discloses a preparation method of a novel sorghum straw adsorbing material. The preparation method comprises the following steps: selecting mature long high sorghum straws, soaking the sorghum straws in tap water and then washing the sorghum straws and drying the sorghum straws till constant weight; then grinding the sorghum straws into powder and sieving the powder; then soaking the powder in deionized water and carrying out enzymolysis with activated amylase and protease; then adding a KOH solution, reacting and then neutralizing the solution with a dilute H2SO4 solution; filtering and airing the solution, then mixing the aired powder with urea in a mass ratio of 1:1 uniformly, re-soaking the mixture in the deionized water and reacting for 5-10 hours; filtering and airing the solution, then washing the product with the deionized water or 95% of alcohol three-four times to remove the residual ionic liquid and drying the product after washing the product, thus obtaining the novel sorghum straw adsorbing material. The adsorbing material is simple in preparation method, is low in cost, is environment-friendly, and has extensive application prospects.

Description

technical field [0001] The invention relates to a sorghum straw adsorption material, in particular to an adsorption material which can be used for treating waste water and a preparation method. Background technique [0002] With the development of industrialization, industrial technology has brought many new products to our life, but it has also caused a lot of pollution to the environment, especially heavy metal pollution. Heavy metal pollution is different from the pollution of other organic compounds. Many organic compounds can be purified physically, chemically or biologically in nature to reduce or eliminate their harmfulness. However, heavy metal pollution sources can be difficult to degrade for decades or even centuries. Heavy metal pollution is mainly pollution of water sources. After these polluted water sources enter the environment or ecosystem, they can be transferred, accumulated, and amplified through the food chain, thus bringing great harm to our lives. [...
