Outline of Final Research Achievements

Layered double hydroxides, which were anion exchangers, were synthesized inside polymer hydrogels in order to improve solid-liquid separation and selectivity for monovalent anions, especially nitrate anions. Those composites for whose preparation agarose gel was used were successfully obtained, and even the composites showed a high selectivity for nitrate when their compositions were adjusted properly. Moreover, it was demonstrated that it was possible to synthesize other composites whose polymer parts were other than agarose and more complexed one that contained porous material.
