Abstract

The anion adsorption behavior of Mg_0.7AI_0.3 O_1.15 prepared by thermal decomposition of a hydrotalcite-like compound, mg_0.7 Al_0.3(OH)₂(CO₃)_0.15^-0.45H₂O, was investigated at 80 °C with initial anion concentration in the solution of 500 ppm and the molar ratio ofMG_0.15 to the anion of 2.5 times the stoichiometric amount shown in eq 2. Mg_0.7AI_0.3O_1.5 is was synthesized by heating in the temperature range from 450 to 900 °C with Mg_0.7AI_0.3O_1.5 (OH)₂as the starting material. It could rapidly rehydrate and adsorb various anions to reconstruct the hydrotalcite-like structure. The degree of adsorption of divalent anions such as CrO₄^2-, HPO_{4₂^-, HV₄2}^-, SiO₃^2-, HGaO₃^2-, and SO₄^2- was more than that of monovalent anions such as Cl^- and MnO₄^-.
