•A luminescent probe of Tb3+-functionalized Zr-MOF was used to detect thiabendazole.•The probe exhibits excellent selectivity and sensitivity toward thiabendazole.•The probe was applied to detect thiabendazole in oranges combined QuEChERS method.•The probe shows great potential practical applications in thiabendazole detection. Thiabendazole (TBZ), has been extensively employed as a pesticide and/or a fungicide in agriculture, while its residues would threaten to public health and safety. Simple, rapid and sensitive probes for detection of TBZ in real food samples is significantly desirable. In present work, a highly selective and sensitive luminescent sensor for monitoring TBZ in oranges has been constructed based on a Tb3+-functionalized Zr-MOF (Tb3+@1). Tb3+@1 exhibited many attractive sensing properties toward TBZ, including broad linear range (0–80 μM), high selectivity, low LOD (0.271 μM) and rapid response time (less than1 min). Moreover, the probe was employed to determine TBZ in real orange samples, in which good recoveries from 98.41 to 104.48% were obtained. It only takes 35 min for the whole process of detection TBZ in real orange samples combined with QuEChERS method. Therefore, this work provided a reliable and rapid method for monitoring the TBZ in real orange samples.
