Abstract

The invention discloses a preparation method and application of a metal-organic polymer-loaded Au-doped quantum dot composite material Au / CdS@Cu(II)-ADM / Cu. Using the electrochemical deposition method, the metal-organic polymer-loaded Au-doped quantum dot composite material working electrode was prepared as a sensor to realize the convenient detection of the content of estriol.

Description

technical field [0001] The invention relates to a preparation method and application of a metal-organic polymer loaded Au-doped quantum dot composite material, and belongs to the technical field of nanometer materials, metal-organic complexes and electrochemical detection. Background technique [0002] As we all know, water is one of the most important natural resources for the survival, reproduction and development of all living things in the world, and it also has an irreplaceable position in economic development and contemporary industrial and agricultural production. However, with the development of society, the number of factories increases, and the pollutants produced gradually increase. In addition, people's awareness of environmental protection is weak, and domestic and industrial sewage is discharged randomly, which pollutes groundwater, rivers, lakes, and seas, seriously affecting people's lives. , The problem of sewage detection and treatment needs to be solved ur...
