Abstract
From the standpoint of resource recovery, a way to convert industrial wastes including iron compounds into functional materials such as an ion-exchanger and a catalyst has been developed. The authors have successful in syntheses of Zn/Fe or Mg/Fe hydrotalcite-like compounds from the wastes. The resulting products including those hydrotalcite-like compounds showed removal properties for PO43- and/or NO3-ions.In the present work, removal-selectivities of the products for PO43- and NO3-ions have been investigated, using anion-mixed solutions in which Cl-, PO43-, NO3- and SO42- ions exist.
