Journal of Molecular Structure Volume 921, Issues 1–3, 17 March 2009, Pages 328-332

The intercalation of (+)-dibenzoyl-d-tartaric acid (DBTA) into Mg–Al layered double hydroxides (LDH-CO3 and LDH-NO3) by ion-exchange method have been investigated. The samples thus obtained were characterized by XRD, FT-IR, DSC-TG, UV, EA and ICP. The results show that the original interlayer carbonate ions and nitrate ions can be replaced by the organic anions under the controlled conditions.
