Deep eutectic solvents (DES) which possess hydrophobicity were synthesized from various carboxylic acid or fatty acids and menthol to remove bisphenol A, a micropollutant present in water-based environments, via liquid–liquid extraction. The bisphenol A concentration was measured quantitatively by ultraviolet-visible spectroscopy. The structure and properties of the DES were examined by Fourier transform infrared spectroscopy and ¹H nuclear magnetic resonance spectroscopy, and the interaction of the cephalic compound was investigated. The menthol–propionic acid and menthol–formic acid DES provided the satisfactory extraction performance and several parameters, including the type and volume, stirring speed, and time of the extraction procedure, were optimized. Excellent recovery rates of 98.2%–99.0% for bisphenol A were obtained under the optimized conditions.

由多种羧酸或脂肪酸和薄荷醇合成具有疏水性的深共熔溶剂（DES），可通过液-液萃取除去双酚A（一种存在于水基环境中的微污染物）。双酚A的浓度通过紫外线-可见光谱法定量测定。用傅立叶变换红外光谱和¹H核磁共振波谱，以及头化合物的相互作用进行了研究。薄荷醇-丙酸和薄荷醇-甲酸DES提供了令人满意的提取性能，并优化了一些参数，包括类型和体积，搅拌速度和提取过程的时间。在最佳条件下，双酚A的回收率极佳，为98.2％–99.0％。
