Abstract

The β-Cyclodextrin epichlorohydrin cross-linked polymer (β-CDP) was synthesized and used as a solid phase extraction material to preconcentrate alizarin dye with UV-Vis spectrophotometer. This method is based on the adsorption of alizarin 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 alizarin dye was found to be ≥ 95%. The proposed method has been applied for the determination of alizarin in various samples.
