Molecular recognitive adsorption of aqueous tetramethylammonium on the organic derivative of Hiroshima University Silicate-1 with a silane coupling reagent.
Hiroshima University Silicate-1 (HUS-1), composed of silicate sheets with a halved sodalite cage and the interlayer tetramethylammonium (TMA) cation in the cage, was modified with dimethyldichlorosilane to form the organic derivative in which a dimethyl group was grafted onto the interlayer surface and a part of the TMA was removed, and the silylated HUS-1 effectively and selectively adsorbed TMA from water even in the presence of aqueous phenol.
