Description

technical field

[0001] The invention belongs to the technical field of solid waste treatment and recycling, and in particular relates to a method for combining infrared spectroscopy and high-efficiency size exclusion chromatography to analyze the functional group composition of humic substances with different molecular weights in organic waste. Background technique

[0002] Humus-like substances are the products of humification and stabilization in the process of organic waste treatment and disposal, and the composition and structure of humus-like substances are closely related to the stability of organic waste. The more humus-like substances synthesized in the process of organic waste treatment, the larger the molecular weight and the higher the content of benzene ring functional groups, the more difficult it is for microorganisms to use, and the more stable the organic waste is. The analysis of the molecular weight of humic substances and the composition of humic substance...
