| description | The invention belongs to the field of sewage treatment, and particularly relates to an efficient nitrate radical treating agent preparation method. According to the preparation method, hydrotalcite with an adjustable and controllable interlayer structure and polypyrrole modified montmorillonite are respectively prepared; hydrotalcite is subjected to delaminating separation to form a dispersed lamellar structure; the surface electrical property of a material is changed by utilizing characteristics of adjustable types and adjustable number of the cations of the hydrotalcite polar plate; steric hindrance is formed by using modification with montmorillonite polypyrrole; and finally the hydrotalcite and the montmorillonite are subjected to composite bonding intercalation to form a layered structure composite material with a certain steric hindrance, wherein the material is applied to adsorption of nitrate radicals in high-salt wastewater (especially high-salt wastewater with high sulfate radical content), and has |
