Extraction and separation device for brown carbon

Abstract

The invention discloses an extraction and separation device for brown carbon and relates to the technical field of brown carbon extraction and separation devices. The extraction and separation devicecomprises a brown carbon generation assembly, a collection assembly and an extraction and separation assembly, wherein the collection assembly is detachably arranged in the brown carbon generation assembly and the brown carbon is convenient to collect; the collection assembly also can be arranged in the extraction and separation assembly and the brown carbon on the collection assembly is convenient to extract and separate; the extraction and separation assembly at least can be used for carrying out water-soluble brown carbon extraction and separation, alkali-soluble brown carbon extraction andseparation and methanol brown carbon extraction and separation on the brown carbon at one time. The extraction and separation device can be used for generating and separating the brown carbon very well, and 7 types of dissolved-state brown carbon such as water-soluble brown carbon, alkali-soluble brown carbon, methanol-soluble brown carbon, hydrophilic brown carbon and hydrophobic brown carbon are finally obtained; various types of brown carbon are conveniently subjected to analysis and chromatographic scanning and are convenient to determine and analyze.

Description

technical field [0001] The invention relates to the technical field of brown carbon extraction and separation devices, in particular to a brown carbon extraction and separation device. Background technique [0002] At present, there are few research reports on the physical and chemical properties of brown carbon produced by biomass and coal combustion at home and abroad, especially [0003] There are few reports on the light absorption characteristics of brown carbon in fine particles from primary combustion emissions. Therefore, in order to study its light absorption properties, it is necessary to separate and extract different brown carbons, especially different solvents to extract different types of brown carbons, so as to facilitate the research and analysis of brown carbons. [0004] However, brown carbon needs to be extracted and separated when it is collected. However, there is no special device for brown carbon extraction and separation on the market, which makes th...

AI Technical Summary

Problems solved by technology

[0004] However, brown carbon needs to be extracted and separated when it is collected. However, there is no special device for brown carbon extraction and separation on the market, which makes the extraction and separation speed of brown carbon low, which brings a lot of inconvenience to the detection test and seriously affects research progress
