Abstract

The invention provides a detection instrument for soil pollutants. The detection instrument for the soil pollutants comprises a feeler lever, a gas guide pipe and a detector; a gas lead-in port is formed at one end of the feeler lever, the other end of the feeler lever is connected with the gas guide pipe; a dust filter is arranged on the gas guide pipe; a data export interface is formed on one side of the feeler lever; the data export port is connected with the detector through a data transmission line; and the detector comprises a photoionization analyzer and an infrared analyzer capable ofworking independently. The detection instrument for the soil pollutants is simple in operation, can perform real-time and on-site detection and can measure the soil pollutants rapidly and effectively;and the test instrument is simple in structure, convenient to use, high in detection speed, high in measuring efficiency, accurate and reliable in measuring result and high in repeatability.

Description

technical field [0001] The invention relates to a detection instrument, in particular to a detection instrument and a detection method for soil pollutants. Background technique [0002] In recent years, the proportion of volatile organic compounds (VOCs) among soil pollutants has been increasing. These substances play an important role in the physicochemical processes of the troposphere because of their important contribution to the formation of ozone and other photochemical oxidants. Due to the toxicity of some of them, such as benzene and buta-1,3-diene, they may also pose serious health hazards to the population and the environment. Specific volatile organic compounds include crude oil products, ie substances and preparations containing aliphatic, cycloaliphatic and aromatic hydrocarbons of low viscosity and low surface tension values. In addition to crude oil itself, it also includes crude oil processing products such as gasoline, kerosene, diesel oil, and mineral oil....
