Abstract

The invention provides a preparation method of a quantum-dot phosphorescent imprinted polymer, belonging to the technical field of preparation of environment function materials. The preparation method comprises the following steps: first, synthesizing Mn-ZnS quantum dots by ZnSO4.7H2O, MnCl2.4H2O and Na2S.9H2O; then, adding (3-mercaptopropyl) trimethoxyl silane (MPTS) to modify to obtain the MPTS-modified Mn-ZnS quantum dots; and then, synthesizing a phosphorescent molecularly imprinted polymer with 2,4,5-trichlorophenol as template molecules by means of hydrolysis of tetraethoxysilane (TEOS) and optically detecting 2,4,5-trichlorophenol by the polymer. The phosphorescent molecularly imprinted polymer is good in optical and pH stability, and has the ability of selectively identifying 2,4,5-trichlorophenol.

Description

Technical field

[0001] The present invention involves a preparation method of a quantum dot phosphorus -printed polymer, which is a technical field of environmental functional materials preparation. Background technique

[0002] In the water environment, 3-chlorophenols, 2,4-dichlorophenol, 2,4,5-trichlorine phenols and 2,4,6-trichlorine phenols have been listed as priority pollutants.The analysis and detection of phenolic pollutants mainly use chromatography, such as liquid chromatography, gas chromatography, and liquid combination.The chromatographic method has high recovery rate, good reproducibility and low detection limit, but requires tedious sample pre -processing processes.Commonly used sample pre -treatment methods include solvent extraction technology, supercritical extraction technology, microwave extraction technology, membrane separation technology, and solid phase extraction technology.Although these methods have their own unique advantages, they also have their own...
