Extraction strategy is designed for the pretreatment of low contents of aromatic N- and S-containing compounds (ANSCs) in environmental waters prior to chromatographic analysis. To enrich studied ANSCs effectively, poly (9-vinylanthracene/4-vinylphenylboronic acid-co-ethylene dimethacrylate/divinylbenzene) polymeric monolithic sorbent were facilely fabricated using the one-step free radical polymerization. Various technologies were employed to investigate the structure and morphology of the resultant monolith. Combining with solid-phase microextraction format, the sorbent exhibited satisfying concentrated performance for ANSCs through multiply interactions under the optimized conditions. After desorption with eluent, the retained analytes were analyzed by HPLC. Results showed that the extraction efficiencies ranged from 51.6 to 93.2%. The linear ranges and limits of detection were 0.01-150 μg/L and 0.63-2.64 ng/L, respectively. Furthermore, the precisions were all below 10%. The introduced approach was productively practiced on three real water samples for simultaneous quantification of studied ANSCs, and the fortified recoveries ranged from 81.5 to 118%. All the results well evidenced that prepared sorbent can enrich ANSCs effectively and the introduced method is reliable alternative for routine analysis of ANSCs in environmental waters.

轻松制造富含官能团的吸附剂，以有效富集环境水中的含氮和含硫化合物的芳香族化合物

萃取策略设计用于在色谱分析之前对环境水中的低含量芳香族含氮和含硫化合物 (ANSC) 进行预处理。为了有效地丰富研究的 ANSC，使用一步自由基聚合轻松制造了聚（9-乙烯基蒽/4-乙烯基苯基硼酸-共聚-乙烯二甲基丙烯酸酯/二乙烯基苯）聚合物整体吸附剂。采用各种技术来研究所得整料的结构和形态。结合固相微萃取形式，吸附剂在优化条件下通过多重相互作用表现出令人满意的 ANSCs 浓缩性能。用洗脱液解吸后，通过 HPLC 分析保留的分析物。结果表明，提取效率在 51.6% 到 93.2% 之间。线性范围和检测限分别为 0.01-150 μg/L 和 0.63-2.64 ng/L。此外，精度均低于 10%。引入的方法在三个实际水样上有效实施，用于同时量化研究的 ANSC，强化回收率范围为 81.5% 至 118%。所有结果都很好地证明了制备的吸附剂可以有效地富集 ANSCs，所引入的方法是环境水域中 ANSCs 常规分析的可靠替代方法。
