Method for rapidly detecting triazole bactericide in water based on HLLME technology of upper critical solution temperature response type eutectic solvent

The invention discloses a method for rapidly detecting a triazole bactericide in water based on an HLLME technology of an upper critical solution temperature response type eutectic solvent, which comprises the following steps: mixing the temperature response type eutectic solvent and a triazole-containing water sample, stirring and heating to a temperature above the upper critical solution temperature of the temperature response type eutectic solvent to form a uniform solution system; then transferring the solution into a centrifugal tube, carrying out ultrasonic treatment and centrifugation, observing that a solution system is divided into an upper layer and a lower layer, collecting a lower-layer phase by using a microsyringe, diluting by using methanol, filtering by using an organic filter membrane, and carrying out HPLC (High Performance Liquid Chromatography) analysis to obtain the content of the triazole bactericide in the water sample; the method is simple, efficient and environment-friendly, a dispers
