What is Solid-phase Extraction Using Molecularly Imprinted Polymer for Selective Extraction of Natural and Synthetic Estrogens from Aqueous Samples about?
A method is proposed for the clean-up and preconcentration of natural and synthetic estrogens from aqueous samples employing molecularly imprinted polymer (MIP) as selective sorbent for solidphase extraction (SPE). The selectivity of the MIP was checked toward several selected natural and synthetic estrogens such as estrone (E1), 17-estradiol (-E2), 17␣-estradiol (␣-E2), estriol (E3), 17␣-ethinylestradiol (EE2), dienestrol (DIES) and diethylstilbestrol (DES). Ultrahigh pressure liquid chromatography (UHPLC) coupled to a TSQ triple quadrupole mass spectrometry (QqQ) was used for analysis of target analytes. The chromatographic separation of the selected compounds was performed in less than 2 min under isocratic conditions. The method was applied to the analysis of estrogens in spiked river and tap water samples. High recoveries (>82%) for estrone, 17-estradiol, 17␣-estradiol, estriol and 17␣-ethinylestradiol were obtained. Lower but still satisfactory recoveries (>48%) were achieved for dienestrol and diethylstilbestrol. The method was validated and found to be linear in the range 50-500 ng L -1 with correlation coefficients (R 2 ) greater than 0.995 and repeatability relative st
