Results and Discussion
To observe the uptake of the textile dyes, the clays were placed in aqueous solutions of the textile dyes and allowed to equilibrate for one day. At the end of this time, HDTMA-bentonite in the aqueous solutions of the textile dyes showed the dark colorations of the original solutions. Na-bentonite had no a_nity for the dyes. Na-clays carry a permanent negative charge in their structural framework. The hydration of Na+ ions in clays and the nature of Si-O groups impart a hydrophilic nature to the mineral surfaces. Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic
chemicals.

To observe the uptake of the textile dyes, the clays were placed in aqueous solutions of the textile dyes and allowed to equilibrate for one day||结果和讨论为了观察织颜料的举起, 泥土被放在织颜料的水解决之内而且允许平衡一天. At the end of this time, HDTMA-bentonite in the aqueous solutions of the textile dyes showed the dark colorations of the original solutions||在这次结束的时候, HDTMA-织颜料的水解决的膨土表示最初解决的黑暗着色. Na-bentonite had no a_nity for the dyes||Na-膨土为颜料没有了 a_nity. Na-clays carry a permanent negative charge in their structural framework||Na-泥土带一项长备的否定费用在他们的结构结构. The hydration of Na+ ions in clays and the nature of Si-O groups impart a hydrophilic nature to the mineral surfaces||Na 的水和+ 在泥土和 Si-O 团体的性质的离子传授到矿物表面的亲水性的自然. Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces||因为吸附在泥土表面上位于,因为这财产,水先取地被这些表面吸附,而且大的有机化合物由于强烈地站得住脚不能够竞争. Thus, Na-clays are ine_ective sorbents for small organic molecules||因此, Na-泥土是小的有机分子的 ine_ective 吸着剂. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions||然而,非常藉由中和层矽酸盐的 anionic 结构藉由使用肯定充满感情的有机种 , 像是 alkylammonim 离子修正泥土的表面财产是可能的. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds||以 modi_ed 形式 (HDTMA-膨土), 泥土表面可能变成 organophilic 而且强烈地以有机化合物互相影响. Textile dyes represent a relatively large group of organic
chemicals||纺织品颜料表现一相对地大群体的有机的化学药品.
