Determination of Bisphenol A in water samples based on magnetic activated carbon andmatrix solid-phase dispersion in high performance liquid chromatography

An analytical method based on magnetic matrix solid phase dispersion( MMSPD) for the determination of Bisphenol A( BPA) in water samples was proposed by high performance liquid chromatography( HPLC)detection. Magnetic activated carbon( MAC) was synthesized for the adsorption of BPA in water samples,and the complete separation of the MAC and the aqueous phase was easily achieved. The influence conditions,such as adsorption time,typeand volume of theelute solvent,elution time,p H and ionic strength of the water sample,were all optimized. Underthe optimized conditions,the limit of detection( LOD) was 0. 02 μg / L,and the linearity was obtained from 0. 05 to 10 μg / L. It was satisfied for the proposed method to be used for the determination of BPA in real water samples.
