Effects of Anion Species on Deintercalation of Carbonate Ions from Hydrotalcite-like Compounds

Abstract

Abstract The deintercalation of carbonate ions from a hydrotalcite-like compound (MgAl-LDH) was investigated using salt-HCl mixed solutions with sodium salts containing various monovalent anion species. The deintercalation was influenced by the anion species, and the carbonate ions were deintercalated most easily for the system containing Cl− or Br− anions.
