A novel hydrophilic magnetic solid phase extraction (MSPE) sorbent with imidazole‐based ionic liquid and adenosine tri‐phosphate (ATP) as bifunctional groups, polydopamine (PDA) as an intermediate layer, Fe3O4 as a magnetic core (Fe3O4@PDA‐ATP@IL) was prepared and applied for selective extraction of phthalic acid esters (PAEs). The resultant Fe3O4@PDA‐ATP@IL performed strong paramagnetic response, excellent water dispersibility, high capacity and selectivity toward PAEs. This strategy exhibited wide linearity (50‐8000 ng/mL), low limit of detection (0.02‐0.80 ng/mL), good recovery (92.3‐105.3%) and good precision (intra‐day RSDs less than 4.8%, inter‐day RSDs less than 6.7%). More encouragingly, under the optimized conditions, the prepared microspheres were applied to analyze nine PAEs in human plasma samples and achieved satisfactory results. The proposed method may open new avenues for analysis of aromatic chemicals in real samples.

亲水性双官能团修饰的磁性微球的制备作为检测人血浆样品中邻苯二甲酸酯的新型基质
以咪唑基离子液体和三磷酸腺苷（ATP）为双官能团，聚多巴胺（PDA）作为中间层，Fe 3 O 4作为磁芯（Fe 3 O ）的新型亲水性磁性固相萃取（MSPE）吸附剂制备了4个（ PDA-ATP @ IL）并用于选择性提取邻苯二甲酸酯（PAE）。生成的Fe 3 O 4@ PDA‐ATP @ IL具有很强的顺磁响应，出色的水分散性，高容量和对PAE的选择性。该策略表现出宽线性（50-8000 ng / mL），低检测限（0.02-0.80 ng / mL），良好的回收率（92.3-105.3％）和良好的精度（日内RSD小于4.8％，每日RSD低于6.7％）。更令人鼓舞的是，在优化的条件下，将制备的微球用于分析人血浆样品中的9种PAE，并获得令人满意的结果。所提出的方法可以为分析真实样品中的芳香族化学物质开辟新的途径。
