Water based-deep eutectic solvent for ultrasound-assisted liquid–liquid microextraction of parabens in edible oil

Extraction of parabens from personal care products using a pH-responsive hydrophobic deep eutectic solvent: experimental design and COSMO-RS evaluations

“…NJC Paperextraction of parabens from edible oil samples28 was comparable with our HDES. The DLLME-DES reported by Bian et al27 revealed higher extraction time and LOD values compared to our method.…”

“…Several research groups also used LLME assisted by different DESs in the extraction of parabens from diverse matrices. 26–29 Three of the published studies were comparable with our method in terms of LODs, extraction time, and repeatability. 26,28,29 Ge et al 26,29 used two different HDESs in the extraction process to confine the solubility of the solvent in an aqueous solution.…”

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

“…The preparation of DESs was achieved by a heating and stirring method according to our previous work with minor modification. 37 Briefly, HBA (TBP) and HBD (M or T) at a molar ratio of 1 : 2 were placed in a flask and continuously stirred at 70 °C until a homogeneous solution without any visual precipitate was observed and then cooled to room temperature. Moreover, TBP–M DESs at a series of molar ratios (3 : 1, 2 : 1, 1 : 1 and 1 : 3) named DES-1, DES-2, DES-3 and DES-5 were also synthesized in the same way.…”
