Abstract

The invention relates to the field of compound analysis, particularly to a method for analyzing diallyl trisulfide in food industry wastewater. According to the method, the pH value of to-be-detectedfood industrial wastewater is adjusted, a certain amount of methanol is added, and the sample is fed to a solid-phase extraction column at a certain flow rate, so that diallyl trisulfide in the to-be-detected sample can be effectively adsorbed and enriched by the solid-phase extraction column; and after the solid-phase extraction column is pumped to be dry, most impurities in the to-be-detected wastewater are removed, and at the moment, a n-hexane or n-hexane-dichloromethane mixed solvent flows through the solid-phase extraction column, so ,hat diallyl trisulfide can be efficiently eluted, primary separation of diallyl trisulfide in food industry wastewater with complex components is realized, the preliminarily separated sample can be used for subsequent detection, and quantitative analysis of diallyl trisulfide in food industry wastewater with complex components and numerous interference factors is realized.

Description

technical field

[0001] The invention relates to the field of compound analysis, in particular to a method for analyzing diallyl trisulfide in food industry wastewater. Background technique

[0002] Diallyl trisulfide is the main component of allicin, which is produced by alliin in fresh garlic being cracked into allicin by allinase, and then further degraded. The molecular formula of diallyl trisulfide is C 6 h 10 S, is a colorless or light yellow liquid with the smell of garlic, insoluble in water and ethanol, miscible in ether, this substance has a strong killing and inhibiting effect on various germs.

[0003] In the actual production of food industries such as garlic and garlic products, a large amount of industrial wastewater containing diallyl trisulfide will be produced. If it is not treated properly in the early stage, it will enter the domestic sewage treatment plant. Because of its obvious bactericidal effect, it will Seriously affect the microbial activity in t...
