| titleOfInvention | Preparation method of selective nitrate adsorbent |
| abstract | The invention belongs to the field of sewage treatment, and in particular relates to a preparation method of a selective nitrate adsorbent. The preparation method of the selective nitrate adsorbent is to prepare hydrotalcite and polypyrrole-modified montmorillonite with adjustable interlayer structure respectively, and firstly, the hydrotalcite is peeled and separated to form dispersed lamellae. Structure, the type and quantity of cations in the hydrotalcite plate can be adjusted to change the surface electrical properties of the material. By intercalating montmorillonite, the modification effect of montmorillonite polypyrrole is increased, and the steric hindrance is formed at the same time. Finally, the composite bond and intercalation of hydrotalcite and montmorillonite are carried out to form a layered structure composite material with certain steric hindrance, which is used to adsorb high-salt wastewater (especially sulfate content Higher nitrate in high-salt wastewater), adsorption selectivity and adsorption capacity have good effects, and the removal rate of nitrate in wastewater is ≥ 70%. |
