Abstract
Two approaches based on emulsification of reverse micelle-based supramolecular solvent microextraction (ERM-SSME) and solidification of vesicle-based supramolecular solvent microextraction (SV-SSME) were compared for the extraction and preconcentration of four triazines (cyanazine, simazine, prometon and propazine) from water samples. Different ERM-SSME and SV-SSME parameters influencing the extraction efficiency were studied and optimized. The results showed that both extraction methods exhibited good linearity, precision, enrichment factor, and detection limit. Under optimal conditions, the limits of detection were 0.3 and 0.5μgL−1 for ERM-SSME and SV-SSME, respectively. The enrichment factors were from 330 to 505 and 285 to 421 for ERM-SSME and SV-SSME, respectively. The applicability of the proposed methods was examined by analyzing triazines in water samples and good results were obtained.
