Hg is one of the most toxic heavy metal ions that exist in the environment and it forms large numbers of toxic binary compounds. Accurate and rapid detection of the concentration of heavy metal ions is a prerequisite technology to achieve pollution control and prevention. Fluorescent probes have attracted extensive attention because of their high sensitivity, prominent precision, convenient and fast visualization of heavy metals. Herein, we report multi-layered graphitic carbon nitride via a simple thermopolymerization treatment as a very effectual fluorescent probe for sensitive and selective detection of Hg with a limit of detection as low as 1.14 nM.
汞是环境中存在的毒性最强的重金属离子之一，它会形成大量有毒的二元化合物。准确、快速地检测重金属离子浓度是实现污染控制与预防的一项前提技术。荧光探针因其高灵敏度、卓越的精准度以及对重金属便捷快速的可视化检测而备受广泛关注。在此，我们报道了通过简单热聚合处理制备的多层石墨相氮化碳，作为一种非常有效的荧光探针，用于灵敏且选择性地检测汞，检测限低至1.14 nM。
