Abstract: A new stir cake sorptive extraction (SCSE) based on molecularly imprinted polymer (MIP) with bisphenol A (BPA) as template was prepared. The effect of preparation conditions on the extraction performance of MIP-SCSE was studied. Then, a methodology combined the stir cake sorptive extraction and liquid desorption, followed by high performance liquid chromatography with diode array detection for the direct analysis of traces of bisphenol A (BPA) in water was developed. To achieve the optimum extraction performance, several main parameters, including pH value and contents of inorganic salt in the sample matrix, extraction and desorption time, were investigated. Under the optimized experimental conditions, the method showed good linearity between 1-200 μg/L for BPA. The detection limit(S/N=3) and quantification limit(S/N=10) of the proposed method for BPA was 0.67 and 2.24 μg/L, respectively. The recoveries of spiked target compound in real samples ranged from 86.2%-112.2%. The MIP-SCSE shows excellent longevity and can be used more than 600 h.
