Hydrotalcite has significant anion exchange properties. For example, when HCl is present, the hydrotalcite's CO32- is easily exchanged with Cl-. Thus, chloride ions are adsorbed and fixed in a stable crystal structure.
Mg 4 .3Al 2 (OH) 12 .6CO 3 -mH 2 O+2HCl
->Mg 4 .3Al 2 (OH) 12 .6Cl 2 -CO 3 - mH 2 O+H 2 O+CO 2
The composition is insoluble in water and oil. In addition, a temperature of about 450 ° C is required for the release of Cl - from the structure.
