Abstract

The development of affordable and ecologically acceptable technologies for heavy metal detection and removal is required due to the rising levels of water and soil pollution. Carbon Dots (CDs) have emerged as a promising nanomaterial for heavy metal detection due to their unique properties. In this study, we report a simple and eco-friendly method to produce CDs using Muntingia calabura fruit extract as a precursor. The hydrothermal method produced a well-defined size, structure, and optical properties of CDs, which were analyzed by using various characterization techniques, including Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDS), Elemental mapping (E-map), UV-visible spectroscopy, X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Photoluminescence (PL) spectroscopy, and Transmission Electron Microscopy (TEM). Additionally, Zeta potential and DLS analysis were used to characterize the CDs. As-synthesized CDs exhibited strong fluorescence emission, making them suitable for the selective determination of Fe3+ ions. The detection limit was found to be 3.6 μM for Fe3+ ions, which highlighted the potential application of as-prepared CDs in environmental monitoring. The green synthesized CDs from Muntingia calabura fruit extract provided a sustainable approach for developing efficient nanoprobes for detecting Fe3+ ions in environmental and biological samples.

用新加坡樱桃提取物制备的碳点荧光测定 Fe3+ 离子

由于水和土壤污染水平不断上升，需要开发经济实惠、生态上可接受的重金属检测和去除技术。碳点（CD）因其独特的性质，已成为一种有前途的重金属检测纳米材料。在本研究中，我们报告了一种以 Muntingia calabura 果实提取物为前体生产 CD 的简单而环保的方法。通过使用各种表征技术，包括场发射扫描电子显微镜（FE-SEM），对 CD 的尺寸、结构和光学特性进行了分析、这些表征技术包括场发射扫描电子显微镜（FE-SEM）、能量色散 X 射线光谱（EDS）、元素图谱（E-map）、紫外可见光谱、X 射线衍射（XRD）、傅立叶变换红外光谱（FT-IR）、光致发光（PL）光谱和透射电子显微镜（TEM）。此外，还使用 Zeta 电位和 DLS 分析来表征 CD。合成的 CD 显示出强烈的荧光发射，使其适用于选择性测定 Fe3+ 离子。从 Muntingia calabura 果实提取物中绿色合成的 CD 为开发用于检测环境和生物样品中 Fe3+ 离子的高效纳米探针提供了一种可持续的方法。
