Abstract

The invention discloses a heavy metal rapid detection sensor for starch products. The heavy metal rapid detection sensor comprises a reaction tank and a sample injection system. The reaction tank includes a three-electrode system, a cleaning system and a discharge system. A counter electrode and a reference electrode of the three-electrode system are integrated on two sides of the reaction tank and fit the tank wall. A working electrode of the three-electrode system is placed in the middle of the reaction tank. The cleaning system comprises nozzles disposed at four corners and a cleaning solution storage chamber communicated with the nozzles. The discharge system is disposed below the reaction tank, and includes a working waste liquid outlet and a cleaning waste liquid outlet. The sensor is in electrical connection with an electrochemical workstation. The heavy metal rapid detection sensor for starch products provided by the invention is equipped with a multi-layer pretreatment mechanism, can perform complete pretreatment on to-be-detected samples, ensures no damage to the working electrode by redundant solid impurities, and improves the service life of the working electrode.

Description

technical field [0001] The invention relates to the technical field of detection of acute toxic substances, in particular to a heavy metal rapid detection sensor for starch products. Background technique [0002] In recent years, my country's industry and agriculture have entered the lane of rapid development. We know that with the rapid development of industry, if the relationship between industrial waste and the environment is not properly handled, it will definitely cause related environmental problems. The problem of environmental protection not only leads to the imbalance of the ecological environment, but also pollutes the natural water system and the atmosphere, thus endangering people's health. Large-scale application of chemical fertilizers and pesticides in agriculture, and excessive pesticides flowing into natural water systems will also aggravate water pollution. [0003] How to effectively monitor and control the deteriorating water environment is an important...
