“…Mercury emissions have attracted an increasing amount of concern due to the high toxicity, volatility, bioaccumulation in the environment and the neurological effects of mercury. According to the Global Mercury Assessment Report, coal-fired power plants are the primary source of anthropogenic emissions of mercury into the atmosphere [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Public concern has recently increased over the potential risk of toxic elements emitted from anthropogenic sources. Among these, mercury has drawn special attention owing to its increasing level of bioaccumulation in the environment and in the food chain, with potential risks for human health. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies, including catalytic oxidation, sorbent injection, photochemistry oxidation, and air pollution control devices.

A novel diarylethene derivative with a Rhodamine B unit was synthesized successfully. It displayed favorable photochromism upon irradiation with UV/vis light. Upon addition of Hg(2+), distinct changes were observed in the absorption and fluorescent spectra due to the formation of a 1:1 ligand/metal complex. As a result, the diarylethene can serve as a fluorescence / colorimetric dual-channel sensor for highly selective and sensitive recognition of Hg(2+) in acetonitrile. Moreover, a complicated logic circuit was constructed with the combinational stimuli of UV/vis, Hg(2+)/ EDTA as input signals and the fluorescence intensity at 605 nm as output signal.
