Abstract

Thiabendazole (TBZ), a widely used agricultural antifungal, has been evidenced to pose serious threat to human health. However, highly sensitive detection of it in food samples is difficult owing to the complexity of food matrix. Herein, an electrochemical sensor, based on multiwall carbon nanotubes (MWCNTs) decorated two-dimensional layered molybdenum disulfide (MoS2), was firstly developed for rapid detection of TBZ using square wave voltammetry method. It is demonstrated that the modification of MoS2 with MWCNTs enhances the catalytic performance to TBZ oxidation. Under optimized conditions, the electrochemical sensor shows admirable linearity range, high selectivity and low detection limit. In pear, water spinach and tap water sample analyses, satisfactory recoveries from 92.83 to 101.92% with coefficients of variation less than 5% were obtained, showing high consistence with the HPLC results. This work puts forward a rapid and reliable method for the highly sensitive screening of the residues of TBZ in food resource.
