Abstract:
2,4,6-trinitrophenyl phenol (TNP) and dichromate (Cr2O72−) have serious toxicological effects on environment. Therefore, it is very important to detect and remove TNP and Cr2O72− in environmental matrix. In this work, a dual-functional UiO type metal-organic framework (Zr-Sti) was synthesized for simultaneous detection and removal of those pollutants in aqueous solution. As for detection, Zr-Sti exhibited sensitive and selective fluorescence response to TNP and Cr2O72− with detection limit below μM level, and possible mechanism behind was proposed and partially supported by experiment data. In addition, adsorption capacity of the prepared Zr-Sti for TNP and Cr2O72− was further investigated to evaluate its performance in pollutant removal from aqueous solution, and the mechanism behinds the obtained high removal efficiency was proposed. These results together with the satisfied recovery for simultaneous detection of TNP and Cr2O72− in real sample, indicate the potential of the prepared Zr-Sti material in the field of environment monitoring and remediation.
