LAYERED COMPLEX HYDROXIDE HAVING HIGH ANION EXCHANGEABILITY AND SUPERIOR STABILITY HARDLY CONTAMINATED WITH CARBONIC ACID, AND ITS SYNTHETIC METHOD

摘要

PROBLEM TO BE SOLVED: To provide a synthetic method for enhancing anion exchangeability and stability hardly contaminated with carbonic acid with respect to a layered complex hydroxide represented by hydrotalcite, hydrokarmite or pyroorite, and to provide a layered complex hydroxide with superior performance obtained by the synthetic method.

SOLUTION: This layered complex hydroxide has high anion exchangeability, causing little carbonic acid contamination by carbon dioxide and carbonic acid ions in air or in water, capable of maintaining expected anion adsorbability over a long period, and having superior stability.
