“…(7) the values of g LV for aqueous solutions of TX-100 and propanol mixtures taken from the literature [29] as well as the measured contact angle values from [25][26] the g SL values are almost constant. It is interesting that the shape of the changes of the surface tension of solution as a function of propanol concentration [29] is similar to the changes of the PTFE-liquid interfacial tension as a function of C 2 , so it is possible that the same expression can describe the changes of g SL vs. g LV . Recently Fainerman and Miller [53,54] proposed an equation which can be used for description of changes of the surface tension of aqueous solutions of ideal surfactant mixtures as a function of their concentration on the basis of the experimental values of the surface tension of aqueous solutions of individual components of a given mixture.…”

After modification this equation was also used successfully for calculation of the surface tension of aqueous solution of TX-100 and propanol mixtures [29]. Therefore, a little modified equation of Miller et al should be applied for description of the changes of the PTFE-water interface tension under the influence of TX-100 and propanol mixture.…”

detector de arranjo de diodos para a determinação de 17β-estradiol (βE2), estrona (E1) e dietilestilbestrol (DES) em água. Ultrassom foi aplicado para auxiliar a emulsificação e Triton X-100 foi usado como dispersor e emulsificante. Tetracloreto de carbono foi usado como solvente extrator. Empregando otimização global, o procedimento foi caracterizado por um intervalo linear aceitável de 10 a 1000 ng mL -1 para βE2, E1 e DES (r > 0,997), exatidão e precisão validadas (RSD 0,85-1,28% (n = 5)) e alta sensibilidade com limites de detecção de 0,200, 0,100 e 0,125 ng mL -1 para βE2, E1 e DES, respectivamente. O procedimento foi aplicado para a análise de amostras típicas de água, com fatores de enriquecimento de 85,29, 173,45 e 97,05 para βE2, E1 e DES, respectivamente, e boas recuperações (≥ 89,82%). De maneira geral, o procedimento desenvolvido foi simples e confiável, com potencial de aplicação em larga escala para análises da água.An ultrasound-assisted surfactant-enhanced emulsification microextraction (UASEME) combined with high performance liquid chromatography-diode array detector procedure was developed for the determination of 17β-estradiol (βE2), estrone (E1) and diethylstilbestrol (DES) in water. Ultrasound was applied to assist emulsification, and Triton X-100 was adopted as the disperser and emulsifier. Carbon tetrachloride was applied as the extraction solvent. Global optimization was used and the developed procedure was characterized by an acceptable linear range of 10 to 1000 ng mL -1 for βE2, E1 and DES (r > 0.997), a validated accuracy and precision (RSD 0.85-1.28% (n = 5)), and high sensitivity with limits of detection of 0.200, 0.100 and 0.125 ng mL -1 for βE2, E1 and DES, respectively. Furthermore, we applied this procedure to analyze typical water samples, with enrichment factors of 85.29, 173.45 and 97.05 for βE2, E1 and DES, respectively, and good recoveries (≥ 89.82%). Altogether, the proposed procedure was simple and reliable, with potential application in large-scale water analysis.

We have developed a synergic microextraction procedure based on ionic liquid for the pre-concentration and determination of glucocorticoids in water samples. Using nonionic surfactant Triton X-100 (TX-100) as synergic reagent, 1-butyl-3-methylimidazolium hexa-fluorophosphate accomplished extraction rapidly without heating in water bath. One key property of ionic liquids that highlights their potential is their wide liquid temperature range. The improved extraction was named as ionic liquid supported vortex-assisted synergic microextraction. Compared with the traditional liquid-liquid extraction and cloud point extraction, ionic liquid supported vortex-assisted synergic microextraction was accomplished in 8 min with considerably high recovery. The proposed method greatly improved the sensitivity of HPLC for the determination of glucocorticoids. The results obtained indicated a good linearity with the correlation coefficient of 0.997 over the range of 0.6-300 ng/mL and high sensitivity with LODs of 4.11, 9.19, and 7.50 ng/mL for hydrocortisone butyrate, beclomethasone dipropionate, and nandrolone phenylpropionate, respectively. The RSD of the method was 1.57-1.81% (n = 6) with enrichment factor of 99.85, and good recovery (≥97.24%). The method was successfully applied to the determination of glucocorticoids in mineral water, water of Dianchi lake, and tap water samples.
