A chemically stable Zr(IV)-based metal-organic framework (BUT-17) has been explored for simultaneous adsorption and determination of bisphenol compounds (BPs) in aqueous medium. The prepared BUT-17 possesses a large surface area (2936 m2 g−1) and excellent fluorescent performance. An adsorption capacity of 111 mg g−1 for bisphenol A (BPA) with a rapid adsorption rate (1.76 g mg−1 min−1) is achieved by BUT-17. The excellent adsorption performance could be attributed to the hydrogen bond interaction between BPs and BUT-17. Furthermore, the fluorescent intensity of BUT-17 was quenched up to 92% due to the formation of complexes between BPs and BUT-17. Thus, a BUT-17-based fluorescent sensing method for the rapid determination of BPs has been established with the limit of detection of 10.0 ng mL−1 for BPA and a linear range from 2.0 to 23.0 μg mL−1. These results indicate that as an outstanding multifunctional platform, BUT-17 is promising for the simultaneous removal and determination of BPs in water medium.

Zr(IV)基金属有机骨架同时吸附测定水介质中双酚类化合物
已经探索了一种化学稳定的基于 Zr(IV) 的金属有机骨架 (BUT-17)，用于同时吸附和测定水性介质中的双酚化合物 (BPs)。制备的BUT-17具有较大的表面积（2936 m 2 g -1）和优异的荧光性能。双酚 A (BPA)的吸附容量为 111 mg g -1，吸附速度快（1.76 g mg -1 min -1) 是通过 BUT-17 实现的。优异的吸附性能可归因于 BPs 和 BUT-17 之间的氢键相互作用。此外，由于 BPs 和 BUT-17 之间复合物的形成，BUT-17 的荧光强度被淬灭了 92%。因此，已经建立了一种基于 BUT-17 的荧光传感方法，用于快速测定 BPs ，BPA的检测限为 10.0 ng mL -1，线性范围为 2.0 至 23.0 μg mL -1。这些结果表明，作为一个出色的多功能平台，BUT-17 有望同时去除和测定水介质中的 BP。
