摘要
L-aspartic acid was intercalated into layered double hydroxides by coprecipitation. Two types of well crystallized material were obtained and were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetry, differential thermal analysis and polarimetry. Schematic models of two intercalation structures with different basal spacings are given. It is proved that the optical activity of L-aspartic acid is retained during and after the intercalation process.
