Abstract

The invention provides a method for determining desoxyquinocetone and 3-methylquinoxaline-2-carboxylic acid in seawater, and belongs to the technical field of detection of pollutants in seawater. According to the method, the MAX column is adopted to enrich and purify the desoxyquinocetone and the 3-methylquinoxaline-2-carboxylic acid in the seawater, so that the determination of the low-concentration desoxyquinocetone and the 3-methylquinoxaline-2-carboxylic acid in the seawater can be realized; and according to the method, the adsorption column is eluted with water to remove most of water-soluble impurities, and then the adsorption column eluted with water is eluted with the ethyl acetate solution of formic acid, so that the content of other substances in the to-be-detected liquid can be reduced, interference on detection of desoxyquinocetone and 3-methylquinoxaline-2-carboxylic acid is avoided, and the detection sensitivity is improved.

Description

technical field

[0001] The invention relates to the technical field of pollutant detection in seawater, in particular to a method for measuring dedioxoquinone and 3-methylquinoxaline-2-carboxylic acid in seawater. Background technique

[0002] The modern aquaculture industry tends to be large-scale and intensive, and the use of antibiotics, vitamins, hormones, and metal trace elements has become an indispensable part of ensuring the development of the mariculture industry. Unfortunately, due to the lack of scientific knowledge and the drive of economic interests, the phenomenon of drug abuse in farming is widespread. The direct consequence of the abuse of veterinary drugs is the residue of veterinary drugs in animal food, which will affect human health after ingestion. The potential harm of veterinary drug residues in animal food to humans has attracted more and more attention. Only the establishment of a set of simple and efficient drug residue determination methods is th...
