Abstract

The invention belongs to the fields of material science and engineering and environmental science, and specifically relates to a temperature-sensitive bisphenol A imprinted polymer microsphere and an application thereof. The microspheres use polystyrene as a carrier, bisphenol A (BPA) as a template molecule, combined with temperature-sensitive material monomers, and polymerize to obtain temperature-responsive BPA imprinted polymer microspheres. The temperature-sensitive bisphenol A imprinted polymer microsphere is used for the detection of bisphenol A. The present invention has clear principle, novel design, low cost and simple operation, adopts methods such as dispersion polymerization, swelling polymerization and precipitation polymerization, and the obtained imprinted polymer microspheres have regular morphology and stable properties, and the adsorption rate of bisphenol A is fast and binding It has high capacity, good specificity and good reproducibility. When applied to the detection of seawater / yogurt samples containing bisphenol A, it can achieve a recovery rate of more than 90% and has good reusability. In addition, the smart imprinted polymer obtained in the present invention is sensitive to external temperature, and different solution temperatures have a great influence on its adsorption capacity.

Description

technical field

[0001] The invention belongs to the fields of material science and engineering and environmental science, and specifically relates to a temperature-sensitive bisphenol A imprinted polymer microsphere and an application thereof. Background technique

[0002] The chemical name of bisphenol A (BPA) is 2,2-bis(4-hydroxyphenyl)propane. It is an important organic chemical raw material and is widely used in plastics and resin products, antioxidants and reaction initiators. About 5% of BPA products are used in food packaging, and flow into the water environment through industrial, agricultural and urban wastewater, becoming a major source of pollution. BPA has become a common endocrine disrupting estrogen in daily life. Studies have confirmed that long-term exposure to excessive levels of BPA can interfere with the balance of the human endocrine system and cause a series of health problems, and its low-dose hazards have also attracted attention. Therefore, there is ...
