Abstract

The invention discloses a chloromethyl polystyrene resin immobilized 1-aminoethyl-3-methylimidazole bromate solid-phase extracting agent as well as a preparation method and application thereof, and belongs to the technical fields of solid-phase extraction and the pretreatment of samples. The chloromethyl polystyrene resin immobilized 1-aminoethyl-3-methylimidazole bromate solid-phase extracting agent is characterized in that the solid-phase extracting agent is made through grafting 1-aminoethyl-3-methylimidazole bromate ionic liquid on the surface of chloromethyl polystyrene resin through chemical bonding; the structural formula of the chloromethyl polystyrene resin immobilized 1-aminoethyl-3-methylimidazole bromate solid-phase extracting agent is as shown in the following descriptions. The invention also specifically discloses the preparation method and the application of the chloromethyl polystyrene resin immobilized 1-aminoethyl-3-methylimidazole bromate solid-phase extracting agent to separation and enrichment as well as the removal of paranitrophenol in a sample. The solid-phase extracting agent provided by the invention has the advantages of being simple and convenient in synthesis method, high in adsorption capacity, good in selectivity, high in anti-interference ability and high in sensitivity and being capable of being recycled, and the like.

Description

technical field

[0001] The invention belongs to the technical field of solid-phase extraction and sample pretreatment, and in particular relates to a chloromethyl polystyrene resin-immobilized 1-aminoethyl-3-methylimidazolium bromide solid-phase extraction agent and a preparation method and application thereof. Background technique

[0002] With the rapid development of industrialization and urbanization, various organic pollutants are discharged into the environment, causing serious environmental problems. p-nitrophenol is an important industrial raw material and intermediate in the production process of medicine, pesticide, dyestuff, artificial resin, explosive and other fine chemicals, and it is easy to enter and pollute water bodies in these production processes. As a common phenolic pollutant in the water environment, p-nitrophenol has carcinogenic, teratogenic, and mutagenic potential toxicity and is difficult to degrade. Even a very low concentration can cause great h...
