| Outline of Final Research Achievements |
Nanocomposite hybrid hydrogels, in which delaminated LDH sheets were uniformly dispersed as isolated nanoplates, were synthesized, and their adsorption abilities for anions was evaluated. Compared with powdery LDH, any particular absorption behavior due to large external surface area was not observed, but accessibility to LDH in the hybrid gels was found to be good either in undried or dried form. In terms of reactivation by using acids in controlled manners, it was found that loss of low-crystallinity LDH by dissolving was greater than that of high-crystallinity LDH.
