Abstract

The invention provides a dibutyl phthalate molecularly imprinted polymer (DBP-MIP) solid phase extraction column and a preparation method and application method thereof, belonging to the technical field of analytical chemistry. The DBP-MIP is prepared by dissolving a template molecule DBP, a functional monomer methacrylic acid and a crosslinking agent ethylene glycol dimethacrylate into a porogen chloroform or acetonitrile, adding an initiator azobisisobutyronitrile, filling nitrogen to remove oxygen, carrying out initiated polymerization at 55-75 DEG C, and grinding, sieving and washing a polymer after completing reaction. The preparation method is characterized by weighing a certain amount of polymer and filling the polymer into a polypropylene column to prepare the solid phase extraction column. The prepared MIP solid phase extraction column can highly selectively separate and enrich DBP in samples such as environment, food, chemical products and the like and effectively remove matrix interference, and has great application values and market prospects.

Description

technical field

[0001] The invention relates to an analytical chemical technology method, in particular to a dibutyl phthalate molecularly imprinted solid-phase extraction small column and a preparation method and application thereof. Background technique

[0002] Dibutyl phthalate (DBP) is mainly used as an industrial plasticizer, as well as a raw material for the production of pesticide carriers, insect repellents, cosmetics, fragrances, lubricants, and defoamers. DBP is widely present in natural environments such as air, water, soil, and organisms as industrial production continues to enter the environment, and has become one of the most common pollutants in the world. DBP is an important environmental endocrine disruptor, similar to estrogen, which seriously interferes with the endocrine system of humans and animals, especially the reproductive function, and has the possibility of carcinogenic, teratogenic and mutagenic, so it has attracted people's attention.
