Title:
METHOD AND APPLICATION FOR DISCRIMINATING SOLUBLE ORGANIC NITROGEN WITH DIFFERENT SOURCES IN SEWAGE
Document Type and Number:
Japanese Patent JP2023002444
Kind Code:
A
Abstract:
To provide a soluble organic nitrogen discrimination method that has high detection throughput, strong versatility, simple and rapid operation, and capable of achieving a qualitative and quantitative discrimination of foreign and endogenous soluble organic nitrogen in sewage.SOLUTION: The method includes the steps of: (1) extracting soluble organic nitrogen in sewage; (2) detecting mass spectral peaks in soluble organic nitrogen extraction liquid; (3) performing preliminary treatment on spectrogram data of a sewage sample; (4) establishing the network relation of material reactions in sewage; (5) screening the material-reaction relation of soluble organic nitrogen; and (6) discriminating soluble organic nitrogen with different sources.SELECTED DRAWING: Figure 1
