A simple and inexpensive method for the preconcentration of trace amounts of bisphenol-A (BPA) in water samples has been examined. Based on quenching of BPA fluorescence signal by copper, BPA was adsorbed on copper-immobilized hydroxylapatite (Cu-HAP). Two minicolumns, one packed with Cu-HAP, and the other packed with HAP, were used to remove BPA from water. The Cu-HAP (6.42�10-2 mg/L BPA � 1.25 %) removed more BPA than HAP (2.04�10-2 mg/L BPA � 3.44 %) at pH 6.00. Optimization of parameters including effect of pH, and flow rate are being investigated. The application of this adsorbent for BPA preconcentration in water samples will be evaluated.
