## Abstract Ionic liquid‐based dispersive liquid–liquid micro‐extraction (IL‐DLLME) was coupled with high‐performance liquid chromatography‐ultraviolet (HPLC‐UV) for the determination of four phthalate esters, including butyl benzyl phthalate, di‐__n__‐butyl phthalate, dicyclohexyl phthalate and bi
Headspace liquid-phase microextraction (HS-LPME) has been applied to efficient enrichment of phenols such as 2-nitrophenol, 4-chlorophenol, 2,4-dichlorophenol, and 2-naphthol from water samples based on 1-butyl-3-methylimidazolium hexafluorophosphate ([C4MIM][PF6]) as an extractant. Some parameters
