Publication date: 2011
Publication number: CN201965114

Abstract: The utility model relates to a device for detecting the tetracycline concentration in a water body, which belongs to the technical field of environment monitoring and comprises a three-electrode electrochemical system and a control detection system. The device is characterized in that a work electrode of the three-electrode electrochemical system adopts a tetracycline molecular imprinting polymer film electrode, the pH valve of electrolyte is ranged from 5 to 8, the work voltage is ranged from 0.2 to 1.0V when a saturated calomel electrode is adopted as a reference electrode, the control detection system comprises a constant potential circuit, an analog-to-digital (A/D) conversion card, a digital-to-analog (D/A) conversion card, a single chip microcomputer, a host machine and a touch display screen, the constant potential circuit is connected with the three-electrode system, an A/D converter and a D/A converter, the single chip microcomputer is connected with the A/D converter, the D/A converter and the host machine, the host machine is connected with the touch display screen, and the setting and the reading of data are realized. The instrument has the advantages that the detection limit value is low, the sensitivity is high, the operation is simple and convenient, the carrying is convenient, and the instrument is applicable to fast in-site detection.
