Abstract

PRECONCENTRATION OF SUDAN I DYE USING ?-CYCLODEXTRIN BUTANEDIOL DIGLYCIDYL ETHER POLYMER AS THE SOLID PHASE EXTRACTANT

Rupinder Kaur, and Dr. Usha Gupta*

ABSTRACT

In this study, a solid phase extraction method has been developed for the preconcentration of Sudan I at trace level using β-cyclodextrin polymer. After preconcentration, the dye solute was determined by UV-VIS spectrophotometry. Various parameters, such as effect of pH, sample solution, shaking time, amount of adsorbent, agitation time for the % uptake of Sudan I has been optimized. This method has been applied for the determination of Sudan I in different food samples.

Keywords: Sudan I dye, ?-Cyclodextrin epichlorohydrin polymer (?-CDP), Preconcentration, Spectrophotometry.
