Description

technical field

[0001] The invention belongs to the technical field of polluted water purification materials, and in particular relates to a bimetallic layered anion polluted water purification material with cation laminates, which can effectively treat anions in polluted water, such as fluoride ions, arsenite and arsenate ions. Good removal. technical background

[0002] In recent years, with the development of the economy and the progress of industry and agriculture, it has brought about the destruction of the living environment of human beings and the destruction of nature. The by-products accompanying the production and use of various products have caused serious environmental pollution. The pollution of fresh water resources that human beings depend on is also increasing day by day. Among water pollution, arsenic pollution has attracted widespread attention. The main form of arsenic in water is arsenite ion (AsO 3 3- ) and arsenate ion (AsO 4 3- ). At the surfac...
