Abstract

This study used a hydrothermal approach to synthesis carbon dots (CDs) from apricot peel, which were then used as a probe for the selective and sensitive detection of Cd2+ ions. The synthesized CDs’ surface groupings, structure, shape, biological nature, and overall size were examined using standard characterization techniques. With a quantum yield of 22.1%, these CDs showed excitation-dependent fluorescence emission. In addition, Cd2+ ions were distinguished from other metal ions by a noticeable drop in fluorescence intensity. The fluorescence probe showed a linear response ranging from 0–300 μM and a detection threshold (DT) of 0.21 μM, indicating its effectiveness for Cd2+ detection. Furthermore, the CDs demonstrated the practical application by detecting Cd2+ ion in actual water samples.
从杨梅中简单绿色合成碳量子点并将其用作选择性灵敏检测 Cd2+ 金属离子的荧光探针
本研究采用水热法从杏皮中合成了碳点(CD),然后将其用作探针,对 Cd2+ 离子进行选择性灵敏检测。利用标准表征技术考察了合成碳点的表面基团、结构、形状、生物性质和整体尺寸。这些光盘的量子产率为 22.1%,显示出与激发相关的荧光发射。此外,Cd2+ 离子与其他金属离子的荧光强度明显降低,从而被区分开来。该荧光探针的线性响应范围为 0-300 μM,检测阈值(DT)为 0.21 μM,表明其在 Cd2+ 检测方面非常有效。此外,CD 通过检测实际水样中的 Cd2+ 离子证明了其实际应用价值。
