英文摘要	National Natural Science Foundation of China [21377105, 21077085]; Scientific Research Foundation for the Returned Overseas Chinese Scholars, State Education Ministry; New Century Excellent Talents in Fujian Province University; In this study, a new boronate affinity sorbent based on poly(4-vinylphenylboronic acid-divinylbenzene) monolith (VPB-DB) was prepared and used as extractive medium of stir cake sorptive extraction (SCSE). The effect of the preparation parameters in the polymerization mixture on extraction performance was investigated thoroughly. The sorbent was characterized by infrared spectroscopy, elemental analysis, scanning electron microscopy and mercury intrusion porosimetry. The determination of 8 sulfonamides in environmental water samples with the combination of SCSE and high performance liquid chromatography tandem mass spectrometry detection was selected as a paradigm for the evaluation of extraction performance of poly(VPB-DB) monolith for nitrogen-containing pollutants. Under the optimal extraction conditions, the limits of detection (S/N= 3) and limits of quantification (S/N= 10) for the target analytes were 0.0012-0.010 and 0.0040-0.033 mu g/L, respectively. The method also showed good linearity, repeatability, recoveries and high feasibility. At the same time, aromatic amines, nitrophenols, amide herbicides and sudan dyes were also used to evaluate the extractive performance of the sorbent for nitrogen-containing compounds. Results well indicate that the interaction of boron-nitrogen coordination between sorbent and analytes plays a key role in the extraction of nitrogen-containing compounds. (C) 2014 Elsevier B.V.
