AB  - Za ekstrakciju estrogenih hormona (estrona, 17β-estradiola i 17α-etinilestradiola) iz vodenih rastvora metodom ekstrakcije na čvrstoj fazi, u ovom radu korišćen je ugljenični kriogel kao sorbent. Metoda ekstrakcije na čvrstoj fazi optimizovana je izborom odgovarajuće mase sorbenta, zapremine i početne pH vrednosti vodenog rastvora hormona, kao i odabirom organskog rastvarača za eluira-nje. Koncentracija ispitivanih hormona u rastvoru nakon ekstrakcije određivana je metodom tečne hromatografije visoke performance u sprezi sa tandem masenom spektrometrijom. Na osnovu prinosa ispitivanih hormona, dobijeni su optimalni parametri metode ekstrakcije na čvrstoj fazi za predkon-centrisanje hormona iz vodenog rastvora: ekstrakcija hormona iz 100 cm3 vodenog rastvora, početne pH vrednosti podešene na 7, vrši se na 20 mg sorpcionog materijala, a smeša dihlormetan/methanol koristi se kao organski rastvarač za eluiranje. Vrednosti prinosa, dobijenih pri optimalnim uslovima, iznosile su od 77 % za estron, do 86 % za 17β-estradiol, uz relativnu standardnu devijaciju od 7,4 do 18 %.
AB  - In this study, carbon cryogel was used as solid-phase extraction sorbent for the extraction of estrogenic hormones (estrone, 17β-estradiol, and 17α-ethinylestradiol) from water solution.
The solid-phase extraction (SPE) method was optimized by choosing an appropriate mass of the sorbent, volume, and initial pH of estrogenic hormone water solution, as well as by choosing an appropriate organic solvent. The concentration of tested hormones after extraction was measured by liquid
chromatography coupled with tandem mass spectrometry. Based on the obtained hormone recoveries, the following optimal conditions of the SPE procedure were chosen: 100 cm3
of hormone water
solution at initial pH adjusted to 7, 20 mg of the sorbent, the methanol-dichloromethane mixture was
used for hormone elution. Recoveries obtained under the optimal conditions ranged from 77 % for
estrone, to 86 % for 17β-estradiol, with relative standard deviation from 7,4 to 18 %.

AB  - This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the influence of surface properties on hormone adsorption, chemical modification of ACCs with HNO3, HCl, or KOH was employed. Applied treatments increased the specific surface area and changed the content of oxygen functional groups. Increased content of acidic surface oxygen functionalities enhanced adsorption efficiency up to 30 % and had a more dominant influence on adsorption capacity than specific surface area. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data fitted well with the Freundlich isotherm model. Calculated mean sorption energy values of 1.4475, 1.3387, and 1.0541 kJ/mol, for E1, E2, and EE2 respectively, indicated that removal of selected hormones was dominated by physisorption mechanism. Obtained Langmuir adsorption capacities, 12.34, 12.66, and 11.11 mg/g for estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol, respectively, as well as convenience of manipulation, recommend activated carbon cloth modified with HNO3 as an efficient adsorbent for removing estrogen hormones from the water.
