Determination of Trace Bisphenol-A in Water Using Three-phase Hollow Fiber Liquid Phase Microextraction Coupled with High Performance Liquid Chromatography
摘要
Abstract
A method for the determination of trace bisphenol-A (BPA) in water was developed by HPLC using three-phase hollow fiber liquid phase microextraction as sample preparation technique. The system of three-phase hollow fiber liquid phase microextraction was designed. The optimized microextraction conditions were as follows: 1-octanol was used as the extraction solvent, the concentration of NaOH solution as acceptor phase was 0. 09 mol/L, the pH value of sample solutions was 4. 0, the NaCl concentration in sample solutions was 30 g/L, the stirring rate was 900 r/min and the extraction time was 60 min. The determination of BPA was finished with injecting 20 μL acceptor phase by HPLC. Under the optimal microextraction conditions, the linear range for BPA was 0. 5 - 200 μg/L (r>0. 999), the detection limits (S/N = 3) of BPA was 0. 2 μg/L, the enrichment factor was 241. 1, and the relative standard deviations (RSD) was lower than 3. 2%. The proposed method was applied to the determination of the BPA in environmental water samples. The spiked average recoveries were within the range of 92.8% -101.9% (w = 3). The developed method is simple and environmentally friendly for the determination of BPA in water.关键词
