Abstract: A new stir bar sorptive extraction (SBSE) based on molecularly imprinted polymer (MIP) with bisphenol A as template was prepared. Based on it, a simple; selective and sensitive method for the determination of bisphenol A (BPA) was developed combined with high performance liquid chromatography (HPLC) with diode array detection. To achieve the optimum extraction performance, several main parameters, including extraction and desorption time, the nature of desorption solvent, pH value and contents of inorganic salt in the sample matrix, were investigated. The optimized parameters for the extraction of BPA from water matrix with the MIP-SBSE are as follows1 extraction and desorption time were 120 min and 10 min, respectively j the pH value of matrix was 10. 0J using acetonitrile (including 1% acetic acid) as desorption solvent; no salt was added in the matrix. Under the optimized experimental conditions; the method showed good linearity between 1. 0 -200 μg/L. The detection limit (S/N = 3) and quantification limit (S/N = 10) of the proposed method for the BPA was 0. 28 μg/L and 0. 94 μg/L, respectively. The proposed method was successfully applied to the determination of the target compound in water samples. The recoveries of spiked target compound in real samples ranged from 96. 0% -108. 7%. The results indicated that the developed method possessed the advantages such as high sensitivity; simplicity; low cost and environmental friendliness
