Detection device and detection method of phenolic volatile organic compounds in soil

Abstract

The invention discloses a detection device and detection method for phenolic volatile organic compounds in soil. The detection device includes a soil sampling mechanism, a supporting base, a phenolicvolatilization generating assembly and a phenolic collection container, wherein the supporting base is arranged on the ground in a supported mode; the soil sampling mechanism is arranged below the supporting base; the soil sampling mechanism extends into the soil below the ground to collect soil samples; the phenolic volatilization generating assembly is arranged above the supporting base; the phenolic volatilization generating assembly collects the soil samples collected by the soil sampling mechanism, and phenolic organic compounds in the soil samples are gasified and volatilized by the phenolic volatilization generating assembly; the phenolic collection container is arranged on the supporting base, and the phenolic collection container contains a solvent solution; and the phenolic collection container collects phenolic gases volatilized from the phenolic volatilization generating assembly, the volatilization of the phenolic organic compounds can be avoided effectively, and the accuracy of soil detection is improved.

Description

technical field [0001] The invention belongs to the field of soil detection, in particular to a detection device and a detection method for phenolic volatile organic compounds in soil. Background technique [0002] Phenolic organic compounds refer to the compounds formed by replacing the hydrogen atoms on the benzene ring in aromatic hydrocarbons with hydroxyl groups. According to the number of hydroxyl groups contained in their molecules, they can be divided into monohydric phenols and polyhydric phenols. The content of phenolic and phenolic organic matter is an important indicator of soil pollution and has received very high attention. At present, the method for determining the content of phenols in soil is: excavate soil samples from the polluted soil, store them in bags, and then send them to the testing room. Factors and the volatile characteristics of some phenolic organic compounds can easily cause the volatilization loss of phenolic organic compounds in soil samples...
