The application discloses a preparation method of a molecular imprinting electrochemical sensor for detecting sodium pentachlorophenol and detection application thereof, and is characterized by comprising the following steps: after ultrasonic dispersion of a sodium pentachlorophenol molecular imprinting polymer suspension, the suspension is drop-coated on the surface of a treated glassy carbon electrode, and the molecular imprinting electrochemical sensor is obtained by standing and drying at room temperature; and a sodium pentachlorophenol detection method is also provided and comprises the following steps: the sensor is placed in a phosphate buffer solution containing Ru(bpy)3 2+ TPrA is polarized, and an initial ECL signal intensity I is recorded; after a to-be-detected PCP-Na solution is added, the ECL intensity I0 is determined by standing and reacting, the ECL signal change value ΔI=I-I0 is taken as a response index, the PCP-Na concentration in the to-be-detected PCP-Na solution is calculated according to the linear relationship between the PCP-Na solution concentration and ΔI, and the method has the advantages of good selectivity and stability, high sensitivity and accuracy.

The invention provides a sodium pentachlorophenate rapid detection kit suitable for bamboo materials and aquatic products, the rapid detection kit is a colloidal gold kit, and the colloidal gold kit comprises a reagent plate, a microporous reagent and a diluent; the diluent is a phosphate composite solution. According to the valve, rapid, efficient and sensitive detection of sodium pentachlorophenate residues in two matrixes is realized, the pretreatment process is simplified, the detection time is shortened, meanwhile, the accuracy and the stability of a detection result are ensured, and the actual requirements of field detection and batch screening are met.
