In this study, for the first time, a simple, inexpensive and sensitive method named
emulsification liquid–liquid microextraction based on deep eutectic solvent (ELLME-DES)
was used for the extraction of benzene, toluene, ethylbenzene (BTE) and seven polycyclic
aromatic hydrocarbons (PAHs) from water samples. In a typical experiment, 100 μL of DES
(as water-miscible extraction solvent) was added to 1.5 mL of sample solution containing
target analytes. A homogeneous solution was formed immediately. Injection of 100 μL of …

In this study, a simple, inexpensive and sensitive method named emulsification liquid–liquid
microextraction based on deep eutectic solvents (ELLME-DES) was used for the extraction
of sulfonamides (SAs) from water samples, including sulfadiazine (SDZ), sulfamerazine
(SMR), sulfametoxydiazine (SDD) and sulfamethoxazole (SMX). In a typical experiment,
eight kinds of DESs (as water-miscible extraction solvents) were added to 1.5 mL of sample
solution containing target analytes, respectively. A homogeneous solution was formed …
