Spectrophotometric determination of Sudan Blue II in environmental samples after dispersive liquid-liquid microextraction
A dispersive liquid-liquid microextraction procedure coupled to spectrophotometry is described for the determination of the trace levels of Sudan Blue II. Analytical parameters, such as pH, volume of extraction solvent (carbon tetrachloride), volume of dispersant (ethanol), volume of sample, and ext...
