采用悬浮聚合法，以与赭曲霉毒素A（OTA）结构类似的醌茜兰为模板分子、α-甲基丙烯酸为功能单体、乙二醇二甲基丙烯酸酯为交联剂制备对OTA有特异性识别作用的醌茜兰分子印迹聚合物（Molecularly Imprinted Polymers，MIPs）。通过单因素实验、正交实验得出MIPs的最佳合成条件。利用红外光谱仪、扫描电子显微镜、激光粒度仪等对聚合物进行表征；吸附性能实验表明MIPs的最大吸附量为4.015 μg/mg。

Quinizarin blue molecularly imprinted polymers (MIPs) that possess specific recognition to ochratoxin A (OTA) are prepared through suspension polymerization method with quinizarin blue as template molecule, α-methylacrylic acid as functional monomer, ethylene glycol dimethacrylate as crosslinking agent, and azobisisobutyronitrile as initiator.The best synthesis conditions for the MIPs are obtained through single factor experiment and orthogonal experiment.The prepared MIPs are characterized by means of infrared spectrometer, scanning electron microscope, laser particle size analyzer and other instruments.It is indicated by adsorption performance experiment that the maximum adsorption capacity of the MIPs to OTA is 4.015 μg·mg^-1.
