【Abstract】 Magnetic solid-phase extraction(MSPE)is one of the most important sample pretreatment techniques.The use of magnetic nanomaterial as adsorbent has gained more attention because the adsorbent combines numerous advantages such as large surface area,unique magnetic property,convenient functional modification,high separation efficiency,easy operation,high reusability and environmental friendliness.This review introduces the preparation and surface modification of the magnetic material,and focuses on the latest progress of the application of MSPE in polycyclic aromatic hydrocarbons,drugs,pesticides,dyes and dye intermediates,phthalates,polychlorinated biphenyls,brominated flame retardants,estrogens,toxic elements and other environmental pollutants in the past one year.In addition,the prospect of MSPE has been discussed in this review.更多还原
