Three types of alkyl-ammonium with different branching chains and three complexants with different functional groups were used to prepare alkyl-ammonium or complexant intercalated montmorillonite nanocomposite (A-Mt or C-Mt). In addition, synergistic intercalated montmorillonite nanocomposites (A/C-Mt) with alkyl-ammonium along with complexant were also prepared. The adsorption performance of the various nanocomposites toward Zn²⁺ and p-nitrophenol (PNP) from simulated binary wastewater containing both Zn²⁺ and PNP were systematically investigated. Characterization of Mt nanocomposites showed that both alkyl-ammoniums and complexants were successfully intercalated into the interlayers of Mt. The surfactant loading amounts of the various nanocomposites were also determined and correlated with the resulting expansion of the interlayer spacing. It was found that intercalation of alkane (OTAC) and –SH (CSH) were conducive to the adsorption of Zn²⁺ while –C₂H₄NH (TETA) and all alkyl-ammoniums were beneficial for PNP adsorption. The extent of adsorption was found to be controlled primarily by pH, i.e., the higher pH had a good effect on the adsorption of both Zn²⁺ and PNP. The adsorption process of Zn²⁺ onto Mt nanocomposites was more in line with the Freundlich model (R² = 0.99), while the Langmuir model described the adsorption of PNP well (R² = 0.99). The adsorption kinetics could be well described by the Elovich equation (R² = 0.98) and the double-constant model (R² = 0.89). Chemical adsorption was determined to be the dominant process between the contaminant and Mt nanocomposite surfaces.

使用三种不同支链的烷基铵和三种不同官能团的络合剂制备烷基铵或络合剂插层蒙脱石纳米复合材料（A-Mt或C-Mt）。此外，还制备了具有烷基铵和络合剂的协同插层蒙脱石纳米复合材料（A/C-Mt）。各种纳米复合材料对Zn ²⁺和对硝基苯酚（PNP）的模拟二元废水中Zn ²⁺的吸附性能和 PNP 进行了系统研究。Mt 纳米复合材料的表征表明，烷基铵和络合剂都成功地嵌入了 Mt 的夹层中。还确定了各种纳米复合材料的表面活性剂负载量，并与由此产生的层间距扩​​大相关联。发现烷烃（OTAC）和-SH（CSH）的嵌入有利于Zn ²⁺的吸附，而-C ₂ H ₄ NH（TETA）和所有烷基铵有利于PNP的吸附。发现吸附程度主要受pH 值控制，即较高的pH 值对Zn ²⁺和PNP的吸附都有良好的影响。Zn ²⁺的吸附过程Mt 纳米复合材料上 的吸附更符合 Freundlich 模型（R ² = 0.99），而 Langmuir 模型很好地描述了 PNP 的吸附（R ²  = 0.99）。吸附动力学可以通过 Elovich 方程 ( R ²  = 0.98) 和双常数模型 ( R ²  = 0.89)很好地描述。化学吸附被确定为污染物和 Mt 纳米复合材料表面之间的主要过程。
