Abstract

The invention discloses an analysis method for determining various pollutant residues in culture water. The analysis method comprises the following steps: carrying out pre-treatment on a culture watersample by adopting ultrasonic assistance and dispersive liquid-liquid micro-extraction; preparing 50 types of standard product solutions of a phthalate type standard product, a disperse dyestuff anda fluorescent brightener and drawing a standard curve; analyzing by utilizing ultrahigh performance liquid chromatography-high-resolution mass spectrometer and carrying out high-throughput determination on the phthalate type standard product, the disperse dyestuff and the fluorescent brightener in the culture water. According to the analysis method disclosed by the invention, 50 types of additiveresidues in a food contact plastic product can be determined simultaneously, the sensitivity is high and the detection limit is 0.1 to 1.0mu g / kg. The method disclosed by the invention has the advantages of sensitivity, rapidness, simplicity, accuracy, time saving, stability and strong practicability and can meet the detection requirements of a current market.

Description

【Technical field】 [0001] The invention relates to an analysis method for determining the residues of various pollutants in aquaculture water, in particular to an analysis method for determining the residues of various pollutants in aquaculture water by using ultrasonic-assisted dispersion liquid-liquid microextraction-ultra-high performance liquid chromatography-high-resolution mass spectrometry , belongs to the technical field of food chemical analysis. 【Background technique】 [0002] In recent years, the speed of economic development in our country is very rapid, and the process of urbanization in our country is also accelerating, and the level of industrialization in our country has also achieved rapid development. The impact of development on the environment has led to serious pollution of water bodies, which is not conducive to the healthy development of aquaculture. Aquaculture is very dependent on a clean and clean water environment. Only when the water body is clean...
