Özet

In this study, a green, simple and sensitive vortex assisted deep eutectic solvent based liquid phase extraction (VA-DES-LPE) method was developed to preconcentrate methyl red from wastewater samples before its determination by UV-Vis spectrophotometry. Deep eutectic solvent (DES) was employed as the extractant for the isolation and preconcentration of methyl red from aqueous solution. Important parameters having effect on the extraction efficiency were investigated and optimized carefully using the "one-factor-at-a-time" approach. Under the determined optimum conditions, limit of detection (LOD) and limit of quantification (LOQ) values were determined as 2.3 and 7.5 mu g/L, respectively. The preconcentration factor was calculated as 35 folds with respect to the developed method. Linearity of the presented method was determined in the range of 8.0-1000 mu g/L. The developed method was successfully applied for the determination of methyl red in wastewater samples, and satisfactory percent recoveries (approximate to 100%) were obtained for different spike concentrations.
