Room temperature ionic liquids are novel solvents with a rather specific blend of physical and solution properties that make them of interest for applications in separation science. In this study, a green, simple, and sensitive sample pretreatment procedure coupled with high-performance liquid chromatography (HPLC) was developed for the analysis of sulfadimidine (SM2) that exploits an aqueous two-phase system based on 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF 4 ) and ammonium sulfate ((NH 4 ) 2 SO 4 ) using a liquid-liquid extraction technique in real environmental water samples. The influences of the concentration of (NH 4 ) 2 SO 4 , pH value, temperature, and concentration of SM2 on the extraction efficiency of SM2 were determined. Under optimal conditions, the extraction efficiencies of SM2 were over 93.7%. Calibration curves yielded good linearity (R 2 = 0.9998) over the range 3-240 ng mL -1 , and the limit of detection and limit of quantification for analytes were 0.9 ng mL -1 and 3 ng mL -1 , respectively. The proposed method was successfully applied to the quantification of SM2 in water samples and recoveries were in the range of 101.2-107%.

Dank Weiterentwicklungen in den Materialwissenschaften und der Fertigungstechnik stehen heute Membranen für stabile Flüssig/Flüssig‐Extraktionsprozesse zur Verfügung. Mit rigorosen Berechnungsmodellen lassen sich sowohl die für eine Trennaufgabe erforderlichen Membranflächen berechnen als auch Optimierungen der Modulform durchführen. In Schnelltests können die prinzipielle Eignung sowie kinetische Parameter ermittelt werden. Damit sind die Voraussetzungen geschaffen, die spezifischen Vorteile dieser Trenntechnik im technischen Einsatz nutzen zu können.

“…The cell membranes of living organisms can be considered as one of these systems [1][2][3]. Additionally, these systems are widely used in research and industry for selective separation and purification of many important materials [4][5][6][7][8][9], and the capability of using membrane selective electrodes in qualitative and quantitative identification carries a latent possibility for their use for sensing and controlling many processes [10]. In environmental fields of application, LMSs are currently attracting great interest, and this interest will increase in the future [11][12][13][14].…”

In this study, a mathematical model for the kinetics of solute transport in liquid membrane systems (LMSs) has been formulated. This model merged the mechanisms of consecutive and reversible processes with a “semi-derived” diffusion expression, resulting in equations that describe solute concentrations in the three sections (donor, acceptor and membrane). These equations have been refined into linear forms, which are satisfying in the special conditions for simplification obtaining the important kinetic constants of the process experimentally.
