China's first high-sensitivity electrochemical detection of heavy metal ions

The reporter learned from the Hefei Institute of Physical Sciences, Chinese Academy of Sciences that the research team of the Institute of Intelligent Science and Technology, Huang Xingjiu, uses TiO2-x nanosheets with a large number of oxygen vacancies on the surface to realize highly sensitive electrochemical detection of heavy metal ions, and to detect heavy metal ions that have plagued people. The mechanism of interference was explored in depth and the principle of “electron-induced interference mechanism” was proposed.
