Sorption of Aniline by Montmorillonite

Abstract

Abstract Sorption of aniline by montmorillonite was studied by infra‐red, X‐ray diffraction and differential thermal analysis methods. The amount of aniline sorbed and the type of bonding depend upon the interlayer cations: anilinium, H + ‐ and Al 3+ ‐ give anilinium aniline ions, NH 4 4 ‐ammonium aniline ions, alkalis and alkaline earths except Cs are bonded to aniline through water bridges and transition metal cations are coordinated to aniline partly directly and partly through water bridges. Sorption does not occur in the complete absence of water.
