采用单滴微萃取和高效液相色谱，开发了一种快速提取内分泌干扰物（包括雌激素和烷基酚）的有效方法。详细评估了影响萃取效率的因素，例如氢键、疏水性、极性和范德华力。结果表明，具有氢键受体且极性较高的溶剂能有效萃取双酚A和雌激素；烷基酚是能够提供强范德华力或具有π-π堆积结构和优异疏水性的首选溶剂。确定了最佳提取条件，包括提取时间、pH 值和盐效应。在优化条件下，获得了高提取因子（≥147）。内分泌干扰物的检测限在 0.33 至 0.67 µg L−1 之间。该方法策略非常适合环境水中痕量内分泌干扰物的测定。
Using single-drop microextraction followed by high performance liquid chromatography, an effective method for the rapid extraction for endocrine disruptors, including estrogens and alkylphenols, was developed. Factors that influenced the extraction efficiency, such as hydrogen bonding, hydrophobic property, polarity, and van der Waals forces, were evaluated in detail. The results indicated that bisphenol A and estrogens were extracted effectively by the solvents with hydrogen bond acceptors and higher polarity; alkylphenols preferred solvents that could supply strong van der Waals forces or possessed π-π stacking structures and superior hydrophobicity. The optimum extraction conditions were determined, including extraction time, pH, and salt effects. Under the optimized conditions, high extraction factors (≥147) were achieved. Limits of detection for the endocrine disruptors were between 0.33 and 0.67 µg L−1. The method strategy is well suited for the determination of trace levels of endocrine disruptors in environmental water.
