Advances on applications of magnetic solid phase extraction technology in the determination of phthalate esters

With the widespread usage of plastics, more and more attention is paid to plasticizers used to improve its properties, such as Phthalate Esters. In the determination of Phthalate Esters, sensitive, simple and fast pre-treatment has become a crucial step. In this paper, the basic concepts of magnetic solid phase extraction and Modification of magnetic solid phase extraction absorbents are briefly introduced, and the research achievements of magnetic solid phase extraction absorbents for the determination of phthalate esters are reviewed in detail. They include magnetic absorbents modified form organic materials, inorganic materials and other materials. The purpose of this paper is to clarify the application method of magnetic solid phase extraction absorbents in the analysis of phthalate esters, and to analyze as well as compare the advantages and disadvantages of different modofication. Finally, the application prospect of magnetic solid phase extraction technology in the determination of phthalate esters is prospected.
