Аннотация
An ultrasonic assisted supramolecular solvent based dispersion solidification liquid–liquid microexraction method was used for the separation and preconcenteration of erythrosine prior to its determination by microspectrophotometry. Under the optimal conditions, the enrichment and preconcentration factors obtained 142 and 33.33 respectively. The calibration curve was linear in the range of 1.0–100 ng/mL of erythrosine with R2 = 0.9949. Detection limit was 0.6 ng/mL and the RSD for 7 replicate determination of 40.0 ng/mL erythrosine was ±1.4%. The applicability of the methods was examined by determining erythrosine in water and beverage samples.
