“…This mesoporous material exhibited selective extraction of target analytes and restricted access for biomacromolecules. Next, UVM-7 was doped with titanium (Ti) to preconcentrate Organophosphorus Pesticides (OPPs) [83] and Organophosphorus Flame Retardants (FRs) [84] in water samples. The matrix compounds of the WWTPs samples affected negatively the recoveries obtained for OPPs and FRs, in the range 48-87% and 65-78%, respectively.…”

Since the first applications of solids with adsorbent properties in water treatment, Solid-Phase Extraction (SPE) has been the most suitable sample preparation technique for the determination of organic pollutants in water. In the last decades, numerous articles have appeared in the literature describing a wide variety of SPE sorbents. Attention in this field has focused on the search for new SPE materials capable of extracting a wide variety of pollutants from water. However, each sorbent has advantages for certain compounds, but not when it is used with others. Thus, conventional sorbents showed poor performance for most high polarity analytes. Recently, mesoporous materials are attracting increasing interest in sample preparation due to their desirable characteristics. They present unique advantages as highly ordered and size-controlled mesoporous structures, high surface areas and large pore volumes, good performance in thermal and chemical stability, compositional controllability and flexibility for functionalization.

Here, an imine‐linked‐based spherical covalent organic framework (COF) was prepared at room temperature. The as‐synthesized spherical COF served as an adsorbent in dispersive solid‐phase extraction (dSPE), by its virtue of great surface area (1542.68 m2/g), regular distribution of pore size (2.95 nm), and excellent stability. Therefore, a simple and high‐efficiency dispersive solid phase extraction method based on a spherical COF coupled with high‐performance liquid chromatography‐tandem mass spectrometry (HPLC‐MS/MS) was established to determine aryl organophosphate esters in biological samples. This approach displayed favorable linearity in the range of 10.0–1000.0 ng/L (r > 0.9989), a high signal enhancement factor (58.8–181.8 folds) with low limits of detection (0.3–3.3 ng/L). Moreover, it could effectively eliminate complex matrix interference to accurately extract seven aryl organophosphate esters from mouse serum and tissue samples with spiked recoveries of 82.0%–117.4%. The as‐synthesized spherical COF has been successfully applied in sample preparation. The dSPE‐HPLC‐MS/MS method based on a spherical COF has potential application to study the pollutants' metabolism in vivo.
