Double-channel in-situ infrared reaction tank

Abstract

The invention provides a double-channel in-situ infrared reaction tank, which comprises a tank body, which a sample groove is formed in the bottom end of the tank body, a sample table is clamped in the sample groove, a clamping groove used for fixing a sample is formed in the top surface of the sample table, and a through hole allowing infrared light to penetrate through is formed in the bottom part of the clamping groove; a first window, a second window and a third window are formed in the side wall of the tank body; a first window sheet and a second window sheet which can transmit infrared light are respectively arranged in the first window and the second window; a third window sheet which can transmit sunlight is arranged in the third window; a gas input pipeline and a gas output pipeline which are communicated with the interior of the pool body are arranged on the pool body; and a reference electrode and a counter electrode are arranged at the top end of the pool body. According tothe double-channel in-situ infrared reaction tank, the first window and the second window are arranged to realize the external reflection channel, and the through holes are formed to realize the internal reflection channel, so that internal reflection and external reflection double-channel light paths are formed, and the in-situ infrared spectrum characterization of liquid-phase species and interface species of the photocatalytic reaction is realized.

Description

Technical field [0001] The invention relates to the technical field of environmental protection, in particular to a dual-channel in-situ infrared reaction tank. Background technique [0002] Photocatalytic degradation of gaseous pollutants is an emerging technology to deal with gas pollution, which has attracted widespread attention from environmental protection organizations and scientific research institutions in various countries. Photocatalytic degradation of gas-phase pollutants belongs to a heterogeneous catalytic system (gas-solid phase), which is a complex multi-step process on the surface of a solid catalyst: reactants diffuse from the gas body to the catalyst surface; reactants are adsorbed on the catalyst surface; The catalyst surface undergoes a chemical reaction; the product desorbs from the catalyst surface; the product diffuses from the catalyst surface into the gas phase. Proving the relationship between the steps involved in adsorption, surface reaction, desorpt...

AI Technical Summary

Problems solved by technology

The existing in-situ ATR test can only select single internal reflection or external reflection mode, which cannot take into account both liquid phase species (more sensitive to external reflection) and interface species (more sensitive to internal reflection), so absolute in-situ analysis cannot be realized
