PRECONCENTRATION OF ERYTHROSINE DYE USING ?-CYCLODEXTRIN EPICHLOROHYDRIN POLYMER AS A SOLID PHASE EXTRACTANT.
Amandeep Kaur*, Dr. Usha Gupta
ABSTRACT
The β-Cyclodextrin cross-linked polymer (β-CDP) was synthesized and used as a solid phase extraction material to preconcentrate erythrosine with UV-Vis spectrophotometer. This method is based on the adsorption of erythrosine on β-CDP. The residual concentration of the dye was determined Spectrophotometrically. The various parameters that were studied are pH; shaking time, sample volume etc. The % recovery of erythrosine dye was found to be ≥ 95%. The proposed method has been applied for the determination of erythrosine in different food samples.
Keywords: ?-cyclodextrin epichlorohydrin polymer (?-CDP), erythrosine dye, preconcentration, solid phase extraction, spectrophotometry.
