A solid phase extraction method for the preconcentration of Brilliant Green (BG) dye at trace level using
β-cyclodextrin polymer. The residual concentration of the dye solute was determined by spectrophotometric method. The effect of various parameters, such as the pH, contact time, amount of adsorbent, sample volume etc. Were observed and discussed. This method has been applied for the determination of Brilliant Green Dye in different food samples such as jelly, mouth freshener etc.
