The invention further relates to a preparation device of the inorganic heavy metal ion adsorption material.

Description

technical field [0001] The invention relates to the field of adsorption material preparation, in particular to an inorganic heavy metal ion adsorption material and a preparation method thereof. Background technique [0002] Water is an indispensable element of environmental resources for human production and life, and the treatment of heavy metal sewage is related to people's quality of life and living environment. At present, there are many methods to deal with and recover heavy metal ions, such as reverse osmosis, ion exchange, membrane filtration and adsorption, among which the adsorption method is widely used because of its low cost, good effect and strong operability. An extremely important physicochemical method in industrial wastewater treatment applications. The key to this technology is the adsorption material. There are many kinds of materials commonly used to prepare adsorbents, which can be roughly divided into two categories: inorganic mineral materials and bi...
