Functionalized magnetic nanoporous carbon derived from banana peel was synthesized through carbonization, porogenesis, carboxylation and magnetization using banana peel and was successfully used as a magnetic solid phase extraction (MSPE) material for the enrichment of six bisphenols (BPs) from beverage and water samples. After the optimization of MSPE process, the enrichment factors of six target analytes were in the range of 74-112 for water samples, and 15-22 for beverage samples. Then, high-performance liquid chromatography-quadrupole-Orbitrap high-resolution mass spectrometry (HPLC-Q Orbitrap-HRMS) was used for the separation and determination of the target analytes. Results showed that the extraction recoveries for 6 BPs were in the range of 71.9-108.4% with an RSD of 2.5-7.5% (n = 6). These results demonstrated that the as-prepared material could efficiently enrich some aromatic compounds and the proposed method is reliable and robust for the determination of BPs in water and beverage samples.
以香蕉皮为原料，通过碳化、成孔、羧基化和磁化等过程合成了功能化磁性纳米多孔碳，并成功将其用作磁性固相萃取（MSPE）材料，用于从饮料和水样中富集六种双酚（BPs）。在优化MSPE过程后，六种目标分析物在水样中的富集因子范围为74-112，在饮料样品中的富集因子范围为15-22。然后，采用高效液相色谱-四极杆-轨道阱高分辨率质谱（HPLC-Q Orbitrap-HRMS）对目标分析物进行分离和测定。结果表明，6种双酚的萃取回收率在71.9-108.4%之间，相对标准偏差为2.5-7.5%（n = 6）。这些结果表明，所制备的材料能够有效地富集一些芳香族化合物，并且所提出的方法对于测定水和饮料样品中的双酚是可靠且稳健的。
