摘　　要：本文以柠檬酸为碳源合成了荧光量子点(CQDs);以呋喃妥因(NFT)为模板分子,甲基丙烯酸为功能单体,正硅酸乙酯为交联剂,乙腈为致孔剂,合成了呋喃妥因分子印迹聚合物(NFT-CQDs-MIP)。用红外光谱法、扫描电镜和荧光光谱法对NFT-CQDs-MIP进行了表征。实验结果表明,NFT-CQDs-MIP对NFT有较好的特异性识别能力,适用于模拟环境水体中NFT的检测。The fluorescent quantum dots(CQDs)were synthesized with citric acid as carbon source.The furantoin molecularly imprinted polymer(NFT-CQDs-MIP)were synthesized from the template molecule of furantoin,with methacrylic acid as the functional monomer,ethyl orthosilicate as the cross-linking agent and acetonitrile as the pore-forming agent.The NFT-CQDs-MIP were characterized by fourier transform infrared spectroscopy,scanning electron microscope and fluorescence spectroscopy.The experimental results showed that NFT-CQDs-MIP has a good specific identification ability to NFT,and it was suitable for the detection of NFT in Simulated water environment.
