摘　　要：以N,N-二甲基甲酰胺(DMF)为溶剂,油酸和油胺作为还原剂在溶剂热的条件下制备出10 nm左右的PdNi纳米立方体,并将其修饰在玻碳电极表面,制备成电化学传感器并将其用于7种检测纺织品和7种食品级塑料包装材料中的三氯生。在最佳实验条件下,电位为1.1V处电化学传感器检测三氯生的线性范围是1.0~150.0μmol·L^(-1);检出限是0.33μmol·L^(-1)。此传感器选择性好、灵敏度高,具有良好的重现性和稳定性。By using N,N-Dimethylformamide as solvent,oleic acid and oleyl amine reduction,PdNi nanocubes were prepared. The triclosan electrochemical sensor were prepared by PdNi nanocubes been modified on the glass carbon electrode,electrochemical sensor has been used in detected triclosan in textile and food plastic packing materials.At the best experiment conditions,the triclosan has been determined at 1. 1V,the liner range of electrochemical sensor is 1. 0 - 150. 0 μmol·L^-1,the detection limit is 0. 33μmol·L^-1.This sensor has good selectivity,high sensitivity,good reproducibility and stability.
