Mercury (Hg) and its derivatives pose a serious threat to the environment and human health. Thus, the development of methods for the selective and sensitive determination of Hg2+ is very important to understand its distribution, and to implement more detailed toxicological studies. Herein, we developed a new method for the detection of Hg2+ based on the tricyanoethylene derivative and mercaptoethanol. This method could selectively detect Hg2+ in a 100% aqueous solution by the naked-eye within the range of 1 - 60 mu M. Importantly, this method also could detect Hg2+ quantitatively by ratiometic absorption spectroscopy in the range of 0.1 - 6 mu M with a detection limit of 55 nM. We anticipate that this proposed method will be used widely to monitor Hg2+ in the environment.
