Abstract

The invention relates to high-selectivity mercury ion colorimetric fluorescence probes. Specifically, the probes provided by the invention are thiocarbonate compounds, and the compounds can be used as the mercury ion colorimetric fluorescence probes for detecting mercury ions. The structure formula of the compounds is described in the description. The probes can realize at least one of the technical effects of realizing high selective identification of the mercury ions, more rapidly responding to the mercury ions, being good in water solubility, being stable in properties and being stored for a long time, and having higher anti-interference ability.

Description

technical field

[0001] The invention relates to a thiocarbonate compound as a fluorescent probe of mercury ions, which can identify mercury ions with high selectivity and sensitivity, or it can measure the concentration of mercury ions in a sample. Background technique

[0002] Mercury is the only liquid metal at normal temperature and pressure. It is a relatively rare element in the earth's crust. A very small amount of mercury exists in the state of simple metal in the natural state. Mercury has many uses, not only can be used to make measuring instruments, such as thermometers, sphygmomanometers, etc.; it can also be used to make pesticides; it can also be used to extract other precious metals (gold) from mineral deposits, etc.

[0003] However, mercury is a heavy metal element, and its harm to the environment and human body cannot be ignored. The main sources of mercury pollution include the combustion of solid waste, wastewater from instrument factories, smelting preci...
