Embodiment 1

[0052] Example 1: Electrochemical Infrared Spectroscopy Combined Method Research Infrared wavenumber greater than 1000cm -1 Pollutant Response

[0053] according to figure 1 To build an electrochemical infrared spectroscopy device, the reaction detection window is diamond, and the conductive

[0054] A device for in-situ characterization of pollutant interface reactions coupled with electrochemical infrared spectroscopy, such as figure 1 As shown: it includes an optical path reflection part, the optical path reflection part includes a housing, and the two sides of the optical path reflection part inside the housing Minute Do not install an optical reflection plate to ensure that the infrared incident light can reach the surface of the detection window, and there are openings on both sides of the housing, which is conducive to the incident of the light source on the detection window. An infrared spectrum detector 2 and a light source 14 are respectively arranged on both sid...

Embodiment 2

[0064] Example 2: Electrochemical Infrared Spectroscopy Method Research Infrared wavenumber is less than 1000cm -1 Pollutant Response

[0065] Based on the influence of some detection windows, the electrochemical infrared spectrometer is at 1000cm -1 The following will be greatly disturbed, so this wave number is the limit, this part studies the 1000cm -1 The following pollutants react. Wastewater discharged from leather factories, printing and dyeing factories and other factories often contains heavy metal chromium, which may cause renal failure or even cancer, and the infrared wave number of chromate is less than 1000cm -1 . Therefore, this part studies the related reactions of chromate pollutants. With hematite (HNC) as the solid-phase reactant, the infrared wavenumber is less than 1000cm -1 The chromate (Cr) and wave number greater than 1000cm -1 The oxalate (OX) reaction in order to explore the applicability of this method to reactants with different wavenumbers. S...

Description

technical field [0001] The invention belongs to the field of environmental chemistry, and specifically relates to a method for in-situ characterization of pollutant interface reaction combined with electrochemical infrared spectroscopy and a device thereof, which is suitable for in-situ characterization of pollutant interface reaction process in simulated soil / groundwater systems, and can obtain synchronous Macro and micro, qualitative and quantitative information. Background technique [0002] With the rapid economic development and accelerated industrialization and urbanization, a large number of pollution problems have emerged in our country. Among them, the interface causes of the pollution process and the mechanism of the remediation process are not clear, which has become a major obstacle to pollution remediation. As far as we know, interface behavior runs through the migration and transformation of pollutants, which is the research frontier in the international envir...
