荧光碳点在重金属离子检测方面的应用

Application of Fluorescent Carbon Dots in Detection of Heavy Metal Ions

重金属离子污染日趋严重,极大地危害了人类的身体健康,如何有效的检测重金属离子成为治理污水的当务之急。荧光碳点作为一种新型的碳纳米材料,具有荧光性质稳定、荧光强度高、低毒性和生物相容性好等特性,在检测重金属离子研究领域引起了极大的研究兴趣。本文综述了荧光碳纳米颗粒在荧光检测Hg^(2+)、Cu^(2+)、Fe^(3+)以及其他金属离子上的最新进展,并对荧光碳点的研究趋势和未来前景进行了展望。

The pollution of heavy metal ions is becoming more and more serious, which greatly harms human health, how to effectively detect heavy metal ions has become a top priority for treating sewage. As a new kind of fluorescent carbon nanomaterials, fluorescent carbon dots (CDs ) have attracted considerable research interest in detecting heavy metal ions due to stable fluorescence, high fluorescence intensity, low toxicity and good biocompatibility. The recent advances of CDs in the fluorescent detection of Hg^2+, Cu^2+, Fe^3+ and other metal ions were reviewed, and the research trends and future prospects of fluorescent CDs were discussed.
