Abstract

At present, with the development of society, different enterprises inevitably produce industrial wastewater and waste residue containing lead and copper. Therefore, there is an urgent need for a rapid and simple method to detect lead and copper in pollutants. In this paper, a metal-organic framework (MOF) doped with Eu(Ⅲ) (Eu³⁺/UiO-66-NH₂) was successfully prepared by one-pot hydrothermal technique. The probe is capable of detecting Pb²⁺ and Cu²⁺ with high sensitivity. Pb²⁺ and Cu²⁺ have detection ranges of 5–340 μM and 0.01–200 μM, respectively. The detection limit for Pb²⁺ was as low as 1.01 μM, and the detection limit for Cu²⁺ was 6.46 μM. This approach has a good detection performance when compared to the method described in the literature. It shows that the prepared sensor has great potential in the detection of actual lead and copper, and provides a practical and effective method for rapid and accurate detection of heavy metal ions.

一种新型（Eu （III）后功能化锆基金属-有机骨架）双发射比例荧光探针的开发，用于快速和高选择性检测Pb2+和Cu2+

目前，随着社会的发展，不同的企业不可避免地产生含铅、含铜的工业废水和废渣。因此，迫切需要一种快速简便的方法来检测污染物中的铅和铜。本文采用一锅水热法制备了铕（Ⅲ）（Eu3+/ uuo -66- nh2）掺杂的金属有机骨架（MOF）。该探针具有探测Pb2+和Cu2+的高灵敏度。Pb2+和Cu2+的检测范围分别为5 ~ 340 μM和0.01 ~ 200 μM。Pb2+的检出限低至1.01 μM， Cu2+的检出限低至6.46 μM。与文献中描述的方法相比，该方法具有良好的检测性能。结果表明，所制备的传感器在实际铅和铜的检测中具有很大的潜力，为快速准确地检测重金属离子提供了一种实用有效的方法。
