Owing to their structural and functional tunability, the preparation of multivariate metal-organic frameworks (MTV-MOFs) and investigation of their potential application has become a hot topic in fields of environment and energy. To achieve more adsorption and removal performance, a series of multivariate Zr-MOFs (TCPP@MOF‐808s) were prepared via mixed-ligands strategy for the first time. The morphology, as well as adsorption and removal properties of TCPP@MOF‐808s can be controlled by adjusting ratio of the linkers. 57%TCPP@MOF-808 could provide ideal appearance with excellent stability. By using 57%TCPP@MOF-808 as sorbent, a dispersive solid-phase extraction (dSPE) was developed for extraction of endocrine disrupting compounds (EDCs) including BPA, 17β-E2, 17α-E2, E1, and HEX from environmental water prior to HPLC analysis. The pseudo-second-order model can describe the adsorption kinetic data well. Using Langmuir isotherm model, the maximum adsorption capacities of BPA, 17β-E2, 17α-E2, and E1 were calculated as 94.34, 104.17, 109.89, and 121.95 mg·g−1, respectively. The LODs for the analysis of EDCs with HPLC-DAD by using 57%TCPP@MOF-808 as sorbent were achieved in the range of 0.01–0.03 ng·mL−1. The recoveries were obtained in the range of 74.63–98.00%. Enrichment factors were calculated in the range of 146–312. This work provides an effective strategy for design and preparation of multifunctional nanomaterials to improve their potential applications in the detection of environmental pollutants.

用于高效吸附内分泌干扰化合物的多元氧化锆金属有机骨架的制备

由于其结构和功能的可调性,多元金属有机框架(MTV-MOFs)的制备及其潜在应用研究已成为环境和能源领域的热门话题。为了获得更高的吸附和去除性能,首次通过混合配体策略制备了一系列多元 Zr-MOFs (TCPP@MOF-808s)。TCPP@MOF-808s的形态以及吸附和去除性能可以通过调节连接体的比例来控制。57%TCPP@MOF-808 可以提供理想的外观和出色的稳定性。以 57%TCPP@MOF-808 为吸附剂,开发了一种分散固相萃取 (dSPE),用于从环境水中提取 BPA、17β-E2、17α-E2、E1 和 HEX 等内分泌干扰物 (EDC)在 HPLC 分析之前。准二级模型可以很好地描述吸附动力学数据。使用Langmuir等温线模型,计算出BPA、17β-E2、17α-E2和E1的最大吸附量分别为94.34、104.17、109.89和121.95 mg·g-1,分别。使用 57%TCPP@MOF-808 作为吸附剂,使用 HPLC-DAD 分析 EDC 的 LOD 范围为 0.01–0.03 ng·mL -1。回收率在 74.63–98.00% 范围内。富集因子的计算范围为 146-312。这项工作为多功能纳米材料的设计和制备提供了一种有效的策略,以提高其在环境污染物检测中的潜在应用。
