Abstract

The invention discloses an on-line detection method for poisonous gas carbon monoxide in imported and exported plastic products. The on-line detection method comprises following steps: a gas sensor is prepared: poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate nanofibers are prepared with an electrospinning technique and applied to a substrate with a surface deposition method to form a gas sensing layer, a non-metal protective layer is arranged on the gas sensing layer, and the gas sensing layer and the non-metal protective layer are combined, assembled and processed, and the gas sensor is formed; the gas sensor, an electrical property detection device and a data processing system are connected to form a gas detection system, the gas sensing layer is contacted and reacts with poisonous gas carbon monoxide, electrical properties of the gas sensor change, the electrical property detection device detects electrical property change data and transmits the data to the data processing system, and the data processing system outputs content of poisonous gas carbon monoxide after analysis and processing. The on-line detection method has the benefits of high detection sensitivity and high detection speed.

Description

technical field [0001] The invention relates to the technical field of quality detection of imported and exported products. More specifically, the present invention relates to an on-line detection method for the toxic gas carbon monoxide in the import and export plastic products during the on-line transportation customs clearance process. Background technique [0002] With the gradual acceleration of the diversification and generalization of online commodity sales, there are more and more types of import and export commodities, and the frequency of import and export is also increasing. However, in order to protect the rights and interests of consumers, the requirements for product quality testing are also increasing. It is getting higher and higher, not only requires fast detection sensitivity, but also fast detection speed to match the fast import and export sales. [0003] Although the quality of illegal plastic products is now more strictly investigated and dealt with, e...
