Simultaneous adsorption and determination of bisphenol compounds in water medium with a Zr(IV)-based metal-organic framework.

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. [ABSTRACT FROM AUTHOR]
