Abstract
Dispersive liquid–liquid microextraction method based on solidification of floating organic droplet (DLLME-SFO) was developed for the analysis of triazines. As model compounds four selected triazine herbicides namely, simazine, atrazine, secbumeton and cyanazine were employed to estimate the extraction efficiency. The experimental conditions were comprehensively studied for the DLLME-SFO method. Under the use of 10μL of 1-undecanol as extraction solvent, 100μL of acetonitrile as disperser solvent and 5% (w/v) NaCl for 3min the results demonstrated that the repeatability (RSD%) of the optimised DLLME-SFO method ranged from 0.03% to 5.1% and the linearity in the range of 0.01–100ppb. Low limits of detection (0.037–0.008ppb), and good enrichment factors (195–322) were obtained. The DLLME-SFO method applied in water and sugarcane samples showed excellent relative recoveries (95.7–116.9%) with RSDs <8.6% (n=3) for all samples.
