[0007] The purpose of the present invention is to provide a preparation method and application of an activated carbon-based inorganic-organic composite material that simultaneously removes arsenic and fluorine ions in drinking water, aiming at the defects of existing drinking water arsenic and fluorine removal materials. Using acidified activated carbon, hydroxyapatite, iron oxyhydroxide, titanium dioxide, acidified clay, chitosan and polyvinyl alcohol as raw materials, the polyvinyl alcohol polymer chain and shell are realized by in-situ polymerization method through organic polymer crosslinking. The interpenetration of polysaccharide polymer chains, with the help of the hydrogen bond between the hydroxyl groups on the polyvinyl alcohol polymer chains and the amino groups and hydroxyl groups on the chitosan chains, forms an interpenetrating network structure, and the activated carbon-based composite materials fully wrapped

Description

technical field [0001] The invention relates to a preparation method of an activated carbon-based inorganic-organic composite material for simultaneously removing arsenic ions and fluorine ions in drinking water. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have also been damaged to varying degrees. Among them, the water quality pollution of drinking water is more serious. With the emergence of many endemic diseases, people gradually realize that the quality of drinking water The importance of security issues. Therefore, the protection of drinking water and the prevention of pollution should attract the attention of the society. [0003] According to the statistical survey and analysis of groundwater quality in nearly 130 cities across the country, the groundwater in most cities and towns has been subjected to varying degrees of point source pollution and non-point source pollution, causing some wat...
