Research Abstract	Layered double hydroxide (LDH) adjusted the crystallite size to less than 20nm was synthesized in Mg-Al and Fe-Zn systems. The LDHs were able to adsorb and to fix the contained harmful negative ions in drainage effectively. The simonkolleite type material that had the bridge structure was selectively formed in a point near the Zn end member of the Fe-Zn system, and selectivity was admitted for Cr (VI) ion. Moreover, it was shown to reproduce in former LDH that had adsorption and the exchangeability of about 95% by the restructuring method.
