More Information
Summary:The invention discloses a method for adsorptively removing sulfate ions in water by using a composite material with a laminated structure. An L-zinc aluminum glutamate hydrotalcite/zinc aluminum nitrate hydrotalcite composite material is prepared by using a co-precipitation method to adsorptively treat the sulfate ions in the water. An experiment shows that absorption of the sulfate ions in the water by using the material has the characteristics of short absorption time, high adsorption capacity, high applicability and recyclability. In addition, the composite material in the method has the advantages of low cost, no pollution and easy separation, and has wide development and application prospects.
