Ion-Exchange Reaction of n-Pentylamine-Intercalated Layered Perovskite with Alkali and Alkaline Earth Metal Ions in Aqueous Solution

Abstract

A layered perovskite type oxide, HCa₂Nb₃O₁₀, can incorporate mono- and divalent metal ions from aqueous solution. n-Pentylamine intercalates into the interlayer of HCa₂Nb₃O₁₀ and the resulting oxide had an excellent reactivity for metal ions such as Cs⁺, Ca²⁺ or Sr²⁺. The mechanism of the intercalation of the metal ions into the hydrophobic interlayer in aqueous medium was studied.
