“…Headspace liquid-phase microextraction using 1-octyl-3-methylimidazolium hexafluorophosphate was applied for extraction of halomethanes, alkyl aromatic compounds (Aguilera-Herrador et al 2008a,b, 2009, and chlorophenols (Peng et al, 2007). 1-Butyl-3-methylimidazolium hexafluorophosphate enabled the separation of chlorobenzenes and chloroanilines (Vidal et al, 2007). Amphetamine and methamphetamine were extracted from urine by the use of solid-phase microextraction employing an immobilized liquid film of 1-ethoxyethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide on a silicone matrix (He et al,2009).…”

“…Vidal et al [7] reported that 1-hexyl-3-methylimidazolium hexafluorophosphate ([H mim ]PF 6 ) hanging single droplet micro-extraction could provide sensitive determination of free benzophenone-3 in human urine samples prior to HPLC. RTILs based headspace single drop microextraction (HS-SDME) was also developed for the sensitive analysis of chlorobenzenes [8], trace DDT and its metabolites [9] with 1-butyl-3-methylimidazolium hexafluorophosphate ([B mim ]PF 6 ). Abulhassani et al [10] optimized hollow fiber LPME (HF-LPME) with [H mim ]PF 6 to extract lead and nickel.…”

As extraction solvents, ionic liquids have green characteristics. In this study, an environmentally benign analytical method termed temperature-controlled ionic liquid dispersive liquid phase microextraction (TIL-DLME) combined with ultra-highpressure liquid chromatography (UHPLC)-tunable ultraviolet detection (TUV) was developed for the pre-concentration and determination of triclosan (TCS), triclocarban (TCC) and methyl-triclosan (M-TCS) in water samples. Significant parameters that may affect extraction efficiencies were examined and optimized, including the types and amount of ionic liquids, volume of the diluent, heating temperature, cooling time, salt effect and pH value. Under the optimum conditions, linearity of the method was observed in the ranges of 0.0100-100 g L 1 for TCS and M-TCS, and 0.00500-50.0 g L 1 for TCC with correlation coefficients (r 2 ) > 0.9903. The limits of detection (LODs) ranged from 1.15 to 5.33 ng L 1. TCS in domestic water and TCC in reclaimed water were detected at the concentrations of 1.01 and 0.126 g L 1 , respectively. The spiked recoveries of the three target compounds in reclaimed water, irrigating water, waste water and domestic water samples were obtained in the ranges of 68.4%-71.9%, 61.6%-87.8%, 58.9%-74.9% and 64.9%-92.4%, respectively. Compared with the previous dispersive liquid-liquid microextraction method (DLLME) about the determination of TCS, TCC and M-TCS, this method is not only more environmentally friendly but also more sensitive.ionic liquid, temperature-controlled ionic liquid dispersive liquid phase microextraction, UHPLC, aqueous samples
