Rapid determination of benzene hydrocarbon in oily wastewater from aromatic unit by headspace-gas chromatography
A gas chromatography headspace method was established for rapid determination of eight benzene series in industrial wastewater.HP Inwax column was used for separation,FID detector was used for detection,and external standard method was adopted for quantification[1].The detection limit was 0.05mg/L.The recovery rate was between 95.83%and 102.68%,with good accuracy.The relative standard deviation was between 0.03%and 0.20%,with good precision.The analysis speed is fast,which meets the requirements of the standard[2].
