Abstract

In this study, Deep Eutectic Solvents (DESs) were utilized for ultrasound -assisted emulsification liquid phase microextraction (UA-ELPME) of Patent Blue V in syrup and water samples. Patent Blue V in sample solution of pH 4.0 was extracted into DES phase prepared from choline chloride and phenol. Concentration of Patent Blue V in final DES phase was measured at 627.5 nm with Uv-Vis spectrophotometry. Sample volume, pH, matrix effect, volume and type of DES, ultrasonication and centrifugation times were investigated and optimized. The developed UA-ELPME method presents a limit of detection (LOD) of 0.37 mu g L-1, preconcentration factor of 15 and a relative standard deviation (RSD, %) of 6.0% under the optimum conditions. The validation was carried out with standard addition-recovery experiments for syrup and water samples. The obtained recovery results showed that the developed UA-ELPME method was applicable for routine Patent Blue V analysis in syrup and water samples.
