چکیده انگلیسی
We investigated the removal of chloride from various solutions (NaCl, HCl, MgCl2, AlCl3, CaCl2, and NH4Cl) at 60 °C for 3 h using magnesium-aluminum oxide, Mg0.80Al0.20O1.10, prepared by the thermal decomposition of a hydrotalcite-like compound, Mg0.80Al0.20(OH)2(CO3)0.10·0.78H2O. The degree of Clâ removal from solution increased with the amount of Mg0.80Al0.20O1.10 used. When Mg0.80Al0.20O1.10 was added to 0.5 M Clâ solutions of HCl, MgCl2, AlCl3, and NH4Cl in a Mg0.80Al0.20O1.10/Clâ molar ratio of 8.75, the degree of Clâ removal exceeded 95%. The degree of Clâ removal from NaCl and CaCl2 solutions was slightly lower, approximately 80 and 90%, respectively. These results reveal that both the amount of Mg0.80Al0.20O1.10 added to chloride solution and the nature of the cations in the solution affect the efficiency of Clâ removal from solution.
