Extraction and Determination of Synthetic Food Dyes in an Aqueous Biphasic System Based on Tetrabutylammonium Bromide

An aqueous biphasic system (ABS) based on tetrabutylammonium bromide (TBABr) with ammonium sulfate as a salting-out agent was used to extract synthetic food dyes from aqueous solutions. Conditions for the preparation of the TBABr–H 2 O–(NH 4 ) 2 SO 4 ABS for microextraction preconcentration of Allur...
