Determination of Polycyclic Aromatic Hydrocarbons in Groundwater with Extraction Standard Correction Method by Solid Phase Extraction |
| |
| Abstract: | Objective]To determine polycyclic aromatic hydrocarbons in groundwater by solid phase extraction and matrix matching.Method]Using solid phase extraction to extract target compound separates target compound,quantitative calculation was conducted by matrix standard.Result]Extraction standard correction method eliminates part matrix effect and when target compound was in low concentration,it will show higher accuracy and precision.Conclusion] LOD was below 2.0 ng/L.Using extraction standard correction method,LOD was always between 10.0-20.0 ng/L and recovery between 70.0%-120.0%. |
