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 m g) and excellent fluorescent performance. An adsorption capacity of 111 mg g for bisphenol A (BPA) with a rapid adsorption rate (1.76 g mg min) 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 for BPA and a linear range from 2.0 to 23.0 μg mL. These results indicate that as an outstanding multifunctional platform, BUT-17 is promising for the simultaneous removal and determination of BPs in water medium. Simultaneous removal and detection of BPs with BUT-17.
一种化学稳定的 Zr(IV) 基金属有机骨架（BUT-17）已被探索用于在水介质中同时吸附和测定双酚化合物（BPs）。所制备的 BUT-17 具有较大的表面积（2936 m g）和优异的荧光性能。BUT-17 对双酚 A（BPA）的吸附容量为 111 mg g，吸附速率很快（1.76 g mg min）。BUT-17 对 BPs 的优异吸附性能可归因于 BPs 与 BUT-17 之间的氢键相互作用。此外，由于 BPs 与 BUT-17 之间形成了配合物，BUT-17 的荧光强度被猝灭了 92%。因此，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，线性范围为 2.0 至 23.0 μg mL。这些结果表明，作为一种出色的多功能平台，BUT-17 有望用于水介质中同时去除和测定 BPs。
