Endocrine disrupting chemicals (EDCs) are emerging water contaminants and efficient elimination is a greater challenge for environmental engineers. The present communication is intended to synthesize the novel dense nanocomposite materials precursors to the bentonite and 3-mercaptopropyletrimethoxy silane/or 3-aminopropyletriethoxy silane. The materials are highly dense, hence the surface area is significantly reduced compared to the pristine bentonite. Further, the materials are intended to be utilized in the elimination of one of the important EDC 17α-ethinylestradiol (EE2). The sorption mechanism is greatly demonstrated based on various parametric studies. It is shown that grafted silane with bentonite network provides enhanced hydrophobicity with organophilic nature and greatly favors the uptake of EE2 at a wide range of pH (5.0–10.0). Relatively rapid uptake of EE2 by the nanocomposite solids followed by a pseudo-second-order kinetic model indicated that the materials are highly efficient for elimination of EE2. Increasing the concentration of EE2 (1.0 to 10.0 mgL⁻¹) favored the extent of removal of EE2 and followed the Langmuir adsorption isotherm. Further, the increase in background electrolytes by 1,000 times did not affect the removal of EE2 by these nanocomposites, indicating the sorbing species are attracted with relatively stronger forces. Moreover, the simultaneous presence of several co-ions did not affect the percentage elimination of EE2; this, perhaps, shows an enhanced selectivity of materials towards the 17α-ethinylestradiol. A high loading capacity of EE2 is achieved under column reactor operation using these nanocomposites. Additionally, the materials are promising in the real matrix treatment.

内分泌干​​扰化学品 (EDC) 是新兴的水污染物，有效消除对环境工程师来说是一个更大的挑战。本通讯旨在合成膨润土和 3-巯基丙基三甲氧基硅烷/或 3-氨基丙基三乙氧基硅烷的新型致密纳米复合材料前体。材料高度致密，因此与原始膨润土相比，表面积显着减少。此外，这些材料旨在用于消除一种重要的 EDC 17 α-炔雌醇（EE2）。基于各种参数研究，极大地证明了吸附机制。结果表明，具有膨润土网络的接枝硅烷提供了增强的疏水性和亲有机性，并极大地有利于在宽 pH 范围（5.0-10.0）下吸收 EE2。纳米复合固体对 EE2 的相对快速吸收，随后的准二级动力学模型表明，该材料对于消除 EE2 非常有效。增加EE2的浓度（1.0至10.0 mgL ^-1) 有利于 EE2 的去除程度并遵循 Langmuir 吸附等温线。此外，背景电解质增加 1000 倍并不影响这些纳米复合材料对 EE2 的去除，这表明吸附物质被相对更强的力吸引。此外，几个共离子的同时存在不会影响 EE2 的消除百分比；这或许表明材料对 17 α-炔雌醇的选择性增强。使用这些纳米复合材料在柱反应器操作下实现了 EE2 的高负载能力。此外，这些材料在真正的基质处理中很有前景。
