Open publisher page 1 citations

Abstract

A rapid determination method for trace bisphenol-A in leachate by solid phase microextraction (SPME) coupled with high performance liquid chromatography (HPLC) was developed. The experimental condition of SPME, such as solid phase microextraction fibers,pH,extraction time, extraction temperature, desorption time, desorption solution,mode and the analytical conditions of HPLC were optimized. The linear range was 12.8～192 μg/L . The correlative coefficient was (0.9975.) The detection limit was 3.25 μg/L(3σ, n=11). The relative standard deviation(RSD)was (4.4%.) The method was used for the determination of trace bisphenol-A in leachate of Qingshan landfill and leachate of Liufang landfill. The recoveries were from 94.5% to 103.3%. This method is fast, convenient, sensitive, solvent free, and suitable for the determination of trace bisphenol-A in leachate.
