Magnetic Solid-phase Extraction Combined with GC-MS for Chlorophenols Analysis in Papermaking Waste water
摘要
Abstract
In this study,magnetic polystyrene(Fe3O4@PS)microspheres were used as adsorbents in solid phase extraction combined with GC-MS to evaluate the efficiency of extracting chlorophenols(CPs)from papermaking wastewater.The novel microspheres were character-ized by transmission electron microscope(TEM),X-ray diffraction(XRD)and fourier-transform infrared spectroscopy(FT-IR).The main influence parameters of the magnetic solid-phase extraction(MSPE),such as the amount of sorbent,extraction time and elution condition,were investigated and optimized.The results demonstrated that 20 mg of sorbent,7 min of desorption time and 2 mL of eluent solvent were chosen as the optimum conditions.Under the optimum conditions,an excellent linearity was observed in the range of 2.5~2000 μg/L.The LODs for chlorophenols were in the range of 0.076~0.207 μg/L and the correlation coefficients ranging from 0.9966~0.9994.The proposed method was successfully applied for the analysis of papermaking wastewater samples with recoveries ranging from 83.39%~109.40%.The above results demonstrated that Fe3O4@PS as a MSPE absorbent performed effective extraction efficiency and simplified operation process in the trace analysis of CPs.关键词
