Preconcentration of Sunset Yellow Dye Using β-Cyclodextrin Butanediol Diglycidyl Ether Polymer as the Solid Phase Extractant

Abstract

A method has been developed for the preconcentration of trace amounts of sunset yellow dye using a newly synthesized β-cyclodextrin butanediol diglycidyl ether polymer (β-CDP). Various parameters such as effect of pH, sample volume, shaking time, agitation time, amount of adsorbent for the % uptake of the sunset yellow have been optimized. β-CDP could be used repeatedly and offered a better recovery of sunset yellow. The method has been for the determination of sunset yellow in different food samples.
