“…Various methods have already been developed for the sulfonamide analysis, such as gas chromatography/mass spectrometry (GC/MS) [13], high-performance liquid chromatography/mass spectrometry (HPLC/MS) [6] and high-performance liquid chromatography (HPLC) [14,15]. Derivatization is a necessary step prior using GC and GC/MS for nonvolatile sulfonamides.…”

A simple, rapid and environment-friendly technique of single-drop liquid-phase microextraction has been developed for the determination of sulfonamides in environmental water. Several important parameters including stirring rate, extraction solvent, extraction pH, salinity and extraction time were optimized to maximize the extract efficiency. Extraction solvent 1-octyl-3-methylimidazolium hexafluorophosphate [C(8) MIM][PF(6) ] ionic liquid showed better extraction efficiency than 1-butyl-3-methylimidazolium hexafluorophosphate [C(4) MIM][PF(6) ] and 1-octanol. The optimum experimental conditions were: pH, 4.5; sodium chloride content, 36% w/v; extraction time, 20 min. This method provided low detection limits (0.5-1 ng/mL), good repeatability (the RSD ranging from 4.2 to 9.9%, n=5) and wide linear range (1-1500 ng/mL), with determination coefficients (r(2) ) higher than 0.9989 for all the target compounds. Real sample analysis showed relative recoveries between 63.5 and 115.8% for all the target compounds.

“…Mobile-phase composition of 20% acetonitrile allowed all analytes to be baseline separated with good resolution in 3 min. The method developed has the highest performance in terms of analytical speed compared with other published HPLC-UV methods for the determination of sulphonamides [10,[30][31][32]. The isocratic mode of separation eliminated the need for re-equilibration, minimizing the turn-around time.…”

High temperature in HPLC is considered a valuable tool helping to overcome the increase in the column backpressure when using small packing particles such as sub-2 μm, as it allows reduction in the mobile-phase viscosity. In this study, a fast analytical method based on HPLC-UV was developed using a sub-2 μm column at elevated temperature for the simultaneous determination of nine sulphonamides. Owing to the lower viscosity of the mobile phase, the separation could be achieved in 3 min at 60°C for all analytes. The effect of temperature, the organic modifier percentage and the flow rate on the retention time was studied. The method developed was used for the determination of selected sulphonamides in surface and wastewater samples. Sample preparation was carried out by solid-phase extraction on Oasis HLB cartridges. The method developed was validated based on the linearity, precision, accuracy, detection and quantification limits. The recovery ranged from 70.6 to 96 % with standard deviations not higher than 4.7%, except for sulphanilamide. Limits of detection ranged from 1 to 10 μg/L after optimization of all analytical steps. This method has the highest performance in terms of analytical speed compared with other published HPLC-UV methods for the determination of sulphonamides in water.

“…Therefore, analysis of SAs residues in the environmental water has drawn increasing concerns. At present, a lot of methods such as enzyme immunoassays [31,32], high performance liquid chromatography (HPLC) [33][34][35][36], gas chromatography [37], and capillary electrophoresis [38] have been used to determine SAs. However, preconcentration and cleanup are usually required prior to determination of SAs due to relatively low SAs concentration in water samples and relative complexity of environmental water matrices.…”

Hexafluoroisopropanol (HFIP)-induced coacervation in aqueous mixed systems of catanionic surfactants of dodecyltrimethylammonium bromide (DTAB) and sodium dodecyl sulfate (SDS) was described in detail, and its application in the extraction of strongly polar sulfonamides (SAs) was investigated. With 10 % (v/v) HFIP inclusion, coacervation formation and two-phase separation occur in a wide range of SDS/DTAB mole ratios (88:12∼0:100 mol/mol) and total surfactant concentrations (10∼200 mmol/L). The interactions between HFIP and DTAB play an important role in coacervation formation. The HFIP-induced SDS-DTAB coacervation extraction proves to be an efficient method for the extraction and preconcentration of SAs. Both hydrophobic interaction and polar interactions (hydrogen-bond, electrostatic, and π-cation) contribute to the distribution of SAs into coacervate phase. The proposed HFIP-induced SDS-DTAB coacervation extraction combined with HPLC-UV was employed for the extraction and quantitative determination of SAs in environmental water samples. Limits of detection were 1.4∼2.5 ng mL(-1). Excellent linearity with correlation coefficients from 0.9990 to 0.9995 was obtained in the concentration of 0.01∼10 μg mL(-1). Relative recoveries were in the range of 93.4∼105.9 % for analysis of the lake, underground, and tap water samples spiked with SAs at 0.01, 1.0, and 10 μg/mL, respectively. Relative standard deviations were 0.7∼3.2 % for intraday precision and 1.3∼4.6 % for interday precision (n = 3). Concentration factors were 17∼49 for three water samples spiked with 0.01 μg/mL SAs. The results demonstrate that the proposed extraction method is feasible for the preconcentration and determination of trace SAs in real water samples.
