Abstract

Novel tributyl phosphate-based hydrophobic deep eutectic solvent: application in simultaneous liquid–liquid microextraction of parabens and their metabolite in surface water samples.

A new magnetic ionic liquid based salting-out assisted dispersive liquid–liquid microextraction for the determination of parabens in environmental water samples

“…The established method was compared with other previously reported methods for enriching and determining the same analytes, and the extraction method, the detection technique, the type and amount of extractants, extraction time and LOQs are summarized in Table 4. The SA-DLLME-HPLC-UV method in the present work just required a short extraction time of 1 min and used a MIL as the extractant compared with most methods 31–34 employing other typical organic solvents. Moreover, the present method exhibited equivalent or lower LOQs than these methods based on common detection techniques such as HPLC-PDA 31 and HPLC-UV, 33,34 except for the hexafluoroisopropanol/Brij-35 supramolecular solvent-based LPME method combined with the HPLC-DAD detection technique 32 with LOQs lower by an order of magnitude.…”

Compared with solid-phase extraction (SPE), 35–37 this method had much higher LOQ values, but the extraction time (1 min) is much shorter than that of SPE (10, 30, 40 min).…”
