•Triazines have been employed as herbicides for crop protection in agricultural domain.•Extraction and analyses of these compounds are very essential in environmental samples.•ERM-SSME and SV-SSME were compared for extraction of four triazine herbicides.•Different parameters influencing extraction efficiencies of both methods were investigated.•Results showed that both extraction methods are suitable for extraction of triazines.
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 0.5 μg L−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.
