LAYERED DOUBLE HYDROXDES WITH TITANIUM DIOXIDE INCORPORATED THEREBETWEEN, ARSENIDE REMOVER COMPRISING THE SAME, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a layered double hydroxide supported with titanium dioxide nanoparticles, an adsorbent for arsenic comprising the same, and a preparation method thereof. According to various embodiments of the present invention, the layered double hydroxide supported with titanium dioxide nanoparticles can be used to oxidize trivalent arsenic ions which are hard to be removed in water to pentavalent arsenic ions easy to be removed while effectively adsorbing and removing arsenic ions.
