Abstract
Introduction
Magnetic Fe3O4 nanoparticles were prepared by coprecipitation and then were coated with SiO2 on the surface.
Materials and methods
Fe3O4@SiO2 composite microspheres were modified by KH570. Using molecular imprinting technology, atrazine magnetic molecularly imprinted polymer was prepared by using atrazine as template molecule, methacrylic acid as functional monomer and ethylene glycol dimethacrylate as cross-linkers. The morphology, composition and magnetic properties of magnetic nanoparticles were characterized. The recognition selectivity of polymer was studied for template molecule and simulation by UV spectrophotometry. The adsorption properties and selectivity ability were analyzed by Scatchard analysis.
Results
Scatchard linear regression analysis indicated that there are two binding sites of the target molecules. The magnetic molecularly imprinted polymer has been applied to the analysis of atrazine in real samples.
Conclusion
The results show that: the recovery rates and the relative standard deviation were 94.0∼98.7% and 2.1∼4.0% in corn, the recovery rates and the relative standard deviation were 88.7∼93.5% and 2.8∼7.2% in water.
