Layered transition metal hydroxide salt (LTMHS) is a group of anion-exchangeable layered compounds. Although LTMHSs have recentely attracted attention of researches on anion exchange and intercalation, very limited numbers of reports have been published on their synthesis, characteristics, and applications. This paper describes basic characteristics of a new LTMHS, nickel-copper hydroxide acetate. Hydrothermal Heating of an aqueous solution containing nickel acetate, copper acetate, and hydrogen peroxide to 150 $^{o}$ C for 4h yielded a layered compound with an analytical composition of NiCu(OH) $_{3.1}$ (OCOCH $_{3}$ ) $_{0.9}$ 0.9H $_{2}$ O. This compound does not take up Cl $^{-}$ and NO $_{3}$ $^{-}$ in aqueous solution but takes up multivalent anions and shows high selectivity in uptake of toxic SeO $_{3}$ $^{2-}$ and AsO $_{4}$ $^{3-}$ . This compound may find applicarion in the removal of those toxic anions form natural water and wastewater rich in Cl $^{-}$ and NO $_{3}$ $^{-}$ .
