Abstract

The invention discloses a mercury ion fluorescence probe compound, a preparation method and an application and relates to the technical field of analytical chemistry. The chemical formula of the mercury ion fluorescence probe compound is obtained through derivatization with 2-(2'-hydroxyphenyl) benzimidazole serving as a parent structure. The probe has good selectivity for mercury ions, is high in sensitivity and easy to prepare and is an ideal mercury ion sensing molecule.

Description

technical field [0001] The invention relates to the technical field of analytical chemistry, in particular to a mercury ion fluorescent probe compound, a preparation method and an application thereof. Background technique [0002] With the continuous development of human society and industrial production, mercury and its compounds have been widely used in metallurgy, electronics, medical and health and other industrial fields. In the above-mentioned industrial production, about 2000-3000 tons of mercury are discharged into the environment in different forms in the waste generated therefrom. Among them, mercury in elemental form is easy to emit, and the generated mercury vapor exists in the air. After the human body absorbs it through the respiratory system and directly contacts it with the skin, it will cause neurotoxicity and kidney poisoning, which seriously endanger human health; Mercury ions can be transformed into organic mercury such as methylmercury under the action ...
