Phenolic environmental estrogens (PEEs) are representative of environmental estrogens, which are commonly known as bisphenol, alkyl phenols, triazine herbicides, and non-steroidal estrogens such as diethylstilbestrol. Diethylstilbestrol is on the list of drugs and other compounds prohibited in food animals. Therefore, the control of its illegal use has become a very urgent problem, and it is very necessary to analyze the estrogen residue in environmental water samples. In this study, molecularly imprinted nanofiber membrane was prepared by electrospinning, and samples were pre-treated with solid phase extraction technology, which was applied to the detection of estrostilbestrol in the environment. For the detection degree of diethylstilbestrol in different water samples, the recovery rate of molecularly imprinted nanofibers was significantly higher than that of blank nanofibers and C18 column. The combination of molecular imprinting and solid phase extraction is effective for the enrichment of trace substances. This study provides an effective method for screening and identification of estrogen in environmental water samples, and further improves the accuracy of detection of corresponding estrogen.
