Critical Reviews in Environmental Science and Technology, Год журнала: 2020, Номер 51(1), С. 44 - 112

Опубликована: Фев. 7, 2020

Sample preconcentration is a critical step in the analysis of trace organic pollutants environmental water. In recent years, solid-phase extraction based on functionalized magnetic nanoparticle (MNP) adsorbents has attracted wide attention because its advantages time, reagent, and labor savings, as well high efficiency. To improve selectivity, dispersibility, stability, reusability MNP adsorbents, various functional materials have been applied, including inorganic materials, carbonaceous compounds, metal–organic frameworks, bio-sorbents their hybrid forms. Here, application for persistent pollutant (POP) detection environment water from 2015 to 2019 reviewed. addition, synthetic routes, characteristics modification selective sorption mechanisms, analytical performance these are also discussed. The properties samples complicated effects efficiency POPs, improvements (MSPE) POP should be carried out with regard following four aspects: (1) development novel applicable adsorbents; (2) choice suitable techniques; (3) combination other (4) automation MSPE.
