[0038] Step 1. SiO 2 Synthesis of Nanoparticles and Manganese-doped ZnS Quantum Dots

[0039] SiO 2 Nanoparticles are in Method based synthesis. Briefly, 30 mL of ethanol and 20 mL of ammonia water (6% by mass) were added to 50 mL of distilled water, and magnetically stirred at room temperature. Then, 5 mL of TEOS and 20 mL of ethanol were added to the solution, and the stirring was continued for 6 h. The product was washed with ethanol and obtained by centrifuge. Finally, it was dried under vacuum at 60°C.

Abstract

The invention provides a preparation method and application of a fluorescent molecularly imprinted adsorption separation material. The method includes the steps of: 1. preparation of SiO2 nano particles; 2. synthesis of manganese doped zinc sulfide quantum dots; 3. preparation of double bond modified SiO2 nano particles; 4. preparation of double bond modified and manganese doped zinc sulfide quantum dots; and 5. preparation of the fluorescent molecularly imprinted adsorption separation material. The preparation method of the surface molecularly imprinted composite photocatalytic material provided by the invention belongs to the technical field of environmental material preparation. The fluorescent molecularly imprinted polymer combines the selectivity of molecularly imprinted polymers and the fluorescence properties of quantum dots, and can realize rapid detection of target molecules through change of the fluorescence intensity.

Description

technical field [0001] The invention belongs to the technical field of environmental material preparation, and specifically refers to a preparation method and application of a fluorescent molecular imprint adsorption separation material. Background technique [0002] Synthetic dibutyl phthalate (DBP) is widely used in agriculture, plastics, industry or consumer products. Since phthalates do not form a stable chemical bond with the product interior, they can leak into the environment and can be detected in water, oil, air, food and living things. In the endocrine system of organisms, a small amount of dibutyl phthalate can cause cancer, deformity and gene mutation. Due to its mutagenic, teratogenic and carcinogenic hazards, China Environmental Monitoring Center and the US Environmental Protection Agency have listed it as a major environmental pollutant. At present, the methods for analyzing and detecting dibutyl phthalate mainly include solid phase extraction (SPE), liquid ...
