Device and method for extracting organic tin in plastic

The invention discloses a device and a method for extracting organic tin in plastic. The device comprises a consumption sample box, a sample room, mechanical tweezers, a leaching-ultrasonic extractionintegration machine, a finished product room, a liquid waste room, a drying fan and an exhaust fan. The consumption sample box is connected with the leaching-ultrasonic extraction integration machinethrough a liquid pump, the mechanical tweezers are arranged between the sample room and the leaching-ultrasonic extraction integration machine, and the leaching-ultrasonic extraction integration machine is connected to the finished product room and the liquid waste room through the liquid pump. The drying fan is successively connected to the leaching-ultrasonic extraction integration machine andthe exhaust fan through a pipeline. The device of the invention can process plastic samples in batches so as to reduce pre-processing time for processing a large number of samples, and improve analysis and detection efficiency
