Abstract

The invention discloses a mercury ion probe GC / HD / AuNS / PT+MB and a preparation method thereof. The method comprises the following steps: firstly, compounding organic functional molecule phenylthiourea PT specifically recognizing and combining with mercury ions, modifying onto an electrode, and adopting a method for electrically depositing gold and nanometer gold ball amplifying signals, thereby acquiring the mercury ion probe GC / HD / AuNS / PT+MB. The invention also provides an application of the mercury ion probe GC / HD / AuNS / PT+MB in detecting mercury ions. The mercury ion probe disclosed by the invention has the advantages of high sensitivity, high accuracy, high selectivity and low detection limit, the detection for mercury ions can be realized, the purpose of effectively removing mercury ions can be achieved, and thus the application prospect is wide.

Description

technical field

[0001] The invention belongs to the analysis and detection technology of organic molecules, and relates to an organic small molecule mercury ion probe for specifically identifying and detecting mercury ions in water samples. Background technique

[0002] As a heavy metal ion that is toxic to the environment and organisms, mercury ions not only cause serious damage to the human digestive system, nervous system, liver and other organs, especially to pregnant women and fetuses, even at very low concentrations can also cause serious damage. The U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO) stipulate that the concentration of mercury ions that can be detected in drinking water must be less than 2ppb. However, real-time determination of low-concentration mercury ions in complex environments and biological systems is still a huge challenge. In addition, mercury pollution is also very serious. In order to deal with mercury pollut...
