Functionalized magnetic nanomaterials as solid-phase extraction adsorbents for organic pollutants in environmental analysis
Abstract
Functionalized magnetic nanomaterials, composed of both organic and inorganic components, have recently been identified as promising solid-phase extraction adsorbents for various applications. Due to their superparamagnetic property, large specific surface area, as well as selective adsorption capacity, this unique class of nanomaterials exhibits an excellent performance in extracting and enriching numerous targeted analytes. This review mainly focuses on the recent advances in the synthesis and application of functionalized magnetic nanomaterials for the preconcentration of organic pollutants in environmental analysis. The development of three kinds of magnetic solid-phase adsorbents, including magnetic polymer nanomaterials, magnetic hybrid nanomaterials and magnetic mesoporous nanomaterials, are elaborated in this review.
