A tricyclazole selective chitosan/Fe₃O₄ magnetic molecularly imprinted polymer (MMIP) was synthesized using non-covalent binding polymerization involving methacrylic acid (MAA) as functional monomer, divinylbenzene (DVB-80) as crosslinker, 2,2'-azobisisobutyronitrile as initiator, acetonitrile/toluene (75:25, v/v) as porogenic solvent and tricyclazole as template. Surface morphology and magnetic characterization of the prepared imprinted and non-imprinted polymers were done using scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectrometry and vibrating sample magnetometry, respectively. The adsorption kinetic data fitted best in pseudo-second-order model. The adsorption equilibrium was achieved in 30 min and the maximum binding capacity was 4579.9 µg/g. The Freundlich isotherm model was found suitable for explaining the binding isotherm data (R² > 0.99). Negative values of thermodynamic parameters ∆G (Gibb’s free energy), ∆H (enthalpy), and ∆S (entropy) revealed exothermic and spontaneous nature of adsorption processes. It also revealed decreased randomness at the solid–liquid interface during sorption. The scatchard plot analysis suggested heterogeneity of binding sites on MMIPs. The molecular recognition selectivity of MMIPs towards tricyclazole was much higher, as compared to its structural analogues, tebuconazole (α = 28.58) and hexaconazole (α = 37.16). The MMIPs were successfully applied to separate and enrich tricyclazole from fortified samples of rice and water, with a recovery percentage of 89.4% and 90.9%, respectively. These reusable imprinted polymers possessing high selectivity and specificity can be utilized as an adsorbent for solid-phase extraction in sample preparation for tricyclazole residue analysis in complex environmental matrices.

三环唑选择性壳聚糖/ Fe ₃ O ₄使用甲基丙烯酸（MAA）作为功能单体，二乙烯基苯（DVB-80）作为交联剂，2,2'-偶氮二异丁腈作为引发剂，乙腈/甲苯（75:25 ，v / v）作为致孔剂，并以三环唑为模板。分别使用扫描电子显微镜，透射电子显微镜，傅立叶变换红外光谱法和振动样品磁法对所制备的印迹和非印迹聚合物的表面形貌和磁性进行了表征。吸附动力学数据最适合拟二阶模型。在30分钟内达到吸附平衡，最大结合容量为4579.9 µg / g。R ²  > 0.99）。热力学参数∆ G（吉布的自由能），∆ H（焓）和∆ S的负值（熵）揭示了吸附过程的放热和自发性质。它也表明吸附过程中固液界面的随机性降低。scatchard图分析表明MMIP上结合位点的异质性。与其结构类似物tebuconazole（α= 28.58）和hexaconazole（α= 37.16）相比，MMIPs对三环唑的分子识别选择性要高得多。MMIPs已成功用于从大米和水的强化样品中分离和富集三环唑，回收率分别为89.4％和90.9％。这些具有高选择性和特异性的可重复使用的印迹聚合物可以用作固相萃取的吸附剂，用于复杂环境基质中三环唑残留分析的样品制备。
