In this work, the efficacy of two metal-organic frameworks (MIL-101(Fe) and NH-MIL-101(Fe)) in eliminating acetamiprid (ATP) insecticide and eosin Y (EY) dye from aqueous solution is tested. An analysis was conducted on the developed nanocomposite's optical, morphological, and structural characteristics. The adsorption isotherm, kinetics, thermodynamics, reusability, and mechanisms for ATP and EY dye removal were assessed. NH-MIL-101(Fe) adsorbed 76% and 90% of ATP pesticide and EY dye, respectively after 10 to 15 min in optimum conditions. For both adsorbents, with regard to explaining the isotherm data, the Langmuir model offered the most accurate description. Moreover, the adsorption of ATP and EY dye is described by the pseudo-second-order kinetic model. The maximum adsorption capacities of ATP and EY dye on MIL-101(Fe) were 57.6 and 48.9 mg/g compared to 70.5 and 97.8 mg/g using NH-MIL-101(Fe). The greatest amount of ATP and EY dye clearance was obtained at a neutral medium for both adsorbents. The results of this investigation demonstrate the effectiveness of MIL-101(Fe) and NH-MIL-101(Fe) as effective substances in the adsorption process for removing pesticides and dyes from aqueous solution.
在这项工作中，测试了两种金属有机骨架（MIL-101(Fe)和 NH-MIL-101(Fe)）在从水溶液中消除乙酰甲胺磷（ATP）杀虫剂和曙红 Y（EY）染料方面的功效。对所开发的纳米复合材料的光学、形态和结构特征进行了分析。评估了吸附等温线、动力学、热力学、可重复使用性和去除 ATP 和 EY 染料的机制。在最佳条件下，NH-MIL-101(Fe)在 10 到 15 分钟内分别吸附了 76%和 90%的 ATP 农药和 EY 染料。对于这两种吸附剂，就解释等温线数据而言，朗缪尔模型提供了最准确的描述。此外，ATP 和 EY 染料的吸附由伪二阶动力学模型描述。与使用 NH-MIL-101(Fe)相比，MIL-101(Fe)对 ATP 和 EY 染料的最大吸附容量分别为 57.6 和 48.9 mg/g，而 NH-MIL-101(Fe)的最大吸附容量分别为 70.5 和 97.8 mg/g。对于两种吸附剂，在中性介质中都能获得最大量的 ATP 和 EY 染料清除率。这项研究的结果表明，MIL-101(Fe)和 NH-MIL-101(Fe)作为从水溶液中去除农药和染料的吸附过程中的有效物质是有效的。
