Abstract

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.

摘要

滨松大学硅酸盐-1（HUS-1）由硅酸盐片组成，其中包含一半的方钠石笼和笼内的四甲基铵（TMA）阳离子，用二甲基二氯硅烷改性形成有机衍生物，其中在层间表面接枝了一个二甲基基团，并且一部分 TMA 被去除，硅烷化的 HUS-1 即使在存在水相苯酚的情况下，也能从水中有效且选择性地吸附 TMA。
