Description

Technical Field

[0001] The utility model belongs to the field of detection technology, in particular to a device for detecting the content of ethylene glycol butyl ether in soil and sediment. Background Art

[0002] With the development of industrialization and urbanization, the problem of organic pollutants in soil and sediments has become increasingly serious. Ethylene glycol butyl ether, as a common organic pollutant, poses a potential threat to the environment and human health. When detecting soil and sediment pollutants, it is inconvenient to pre-treat the soil and sediment, so there are the following deficiencies in its use:

[0003] 1. Currently, when testing the content of ethylene glycol butyl ether in soil and sediment, the soil and sediment need to be dried. The drying efficiency is not high, and the drying process may take a long time, which may extend the overall testing cycle.

[0004] 2. At the same time, the dried soil and sediment need to be crushed. Low crushing efficiency may cause uneven samples, thus affecting the accuracy of the analysis results.

[0005] To this end, we proposed a detection device for the content of ethylene glycol butyl ether in soil and sediment. Utility Model Content
