Problems solved by technology

However, these extractants are highly toxic and volatile, and can easily cause great harm to operators and the environment
Moreover, traditional DLLME based on organic dispersing solvents has several serious drawbacks, such as possible loss of extraction solvent, penetration of analyte into dispersant, reduced extraction efficiency, etc.

Abstract

The invention discloses a method for rapidly extracting a phenol endocrine disruptor in plastic package beverage, and belongs to the technical field of phenol endocrine disruptor detection. The extraction method comprises the steps of accurately weighing sodium caprylate, citric acid and sodium bicarbonate, and performing pressing formation for use, wherein the mass ratio of the sodium caprylate,the citric acid and the sodium bicarbonate is 1:1:0.4; weighing a to-be-detected sample in a container, placing an effervescent tablet, pressed in advance, in the to-be-detected sampled, and performing centrifugation after reaction is completed; and performing ice-water bath on the to-be-detected sampled after centrifugation so that an upper-layer organic phase is converted to a solid phase, and collecting the organic phase of the solid phase. A green convertible hydrophilic solvent s used as an extraction agent, the extraction agent can be grown in an in-situ way, the dispersion of the extraction agent is helped by CO2 bubbles generated by reaction of the citric acid and sodium bicarbonate, and the extraction agent is fully combined with a target; and a suspension curing method is used for collecting, the recycling rate of the target is greatly improved, and moreover, organic matter separation is very simple and rapid.

Description

technical field [0001] The invention relates to the technical field of detection of phenolic endocrine disruptors, in particular to a method for rapidly extracting phenolic endocrine disruptors in plastic packaged drinks. Background technique [0002] Bisphenol A (BPA), nonylphenol (NP) and octylphenol (OP) are endocrine disrupting chemicals that are plasticizers used to increase the flexibility, transparency and durability of plastics and are used in the manufacture of Certain plastics such as microwave lunch boxes, baby bottles, water dispenser buckets, etc. Many foods and beverages are packaged in plastic. And bisphenols can be released from plastic packaging and migrate into beverages and foods, especially when they come into contact with acidic or alkaline ingredients. They can mimic the adverse effects of estrogen on human reproduction and development, damaging neural networks, cardiovascular, metabolic and immune systems. Therefore, there is an urgent need for rapi...
