A new FeO@SiO fluorescent probe for detection of Hg in aqueous solutions was introduced based on a simple ligand. The prepared sample was characterized by using TEM, EDX, FT-IR, VSM, and TGA/DTA. The sensitivity of the probe toward Hg and its selectivity in presence of other cations were proven by using fluorescence spectroscopy. The detection limit of the prepared chemosensor is 8.1 nM. The magnetic property of the prepared nanocomposite enables its separation by an external magnet. The simple structure of the employed ligand results in simple preparation procedure and therefore could be an applicable material for detection of Hg in industrial, environmental, and biological samples.
基于一种简单的配体，引入了一种用于检测水溶液中汞的新型FeO@SiO荧光探针。通过透射电子显微镜（TEM）、能量色散X射线光谱（EDX）、傅里叶变换红外光谱（FT-IR）、振动样品磁强计（VSM）和热重/差示热分析（TGA/DTA）对制备的样品进行了表征。通过荧光光谱证明了该探针对汞的灵敏度及其在其他阳离子存在下的选择性。制备的化学传感器的检测限为8.1 nM。制备的纳米复合材料的磁性使其能够通过外部磁铁进行分离。所用配体的简单结构导致制备过程简单，因此可能是用于检测工业、环境和生物样品中汞的适用材料。
