摘要：

In this paper, a luminescent metal-organic framework Tb3+@tartaric acid-functionalized Zr-MOF (Tb3+@UiO-67-bpy-TA, TA = tartaric acid) was prepared by post-synthetic modification (PSM) and used as a fluorescence sensor for the detection of the pesticide nitenpyram (NTP). The fluorescence sensing experiment verified that Tb3+@UiO-67-bpy-TA had exceptional sensitivity and selectivity for NTP detection, and the detection limit was calculated to be as low as 1.28 mu M. The mechanism studies indicated that competitive UV absorption, photoinduced electron transfer (PET) and dynamic quenching contributed to the fluorescence quenching process. In addition, the detection of NTP in tap water and Yellow River water samples by the Tb3+@UiO-67-bpy-TA were also investigated using standard addition method, and satisfactory recoveries were achieved.
