Abstract:
A method for the determination of bisphenol A, octyphenol, nonylphenol in water samples was developed using stir bar sorptive extraction (SBSE) based on poly (vinylimidazole-divinylbenzene) monolithic material (SBSEM) combined with high performance liquid chromatography with diode array detection.To achieve the optimum extraction performance, several main extraction parameters, including extraction and desorption time, pH value and contents of inorganic salt in the sample matrix, were investigated.Under the optimized experimental conditions, the method showed good linearity and repeatability, low detection limits (S/N = 3) and quantification limits (S/N = 10) of the proposed method for the target compounds were achieved within the range of 0.13-0.66 and 0.44-2.19 μg/L, respectively.The extraction performance of SBSEM to the target compounds was also compared with commercial SBSE which used polydimethylsiloxane as coating.The proposed method was successfully applied to the determination of the target compounds in water samples.The recoveries of spiked target compounds in real samples ranged from 37.8%-101.1%.The results indicated that the developed method possessed advantages such as sensitivity, simplicity, low cost and high feasibility.
