Quantification of phenol in surface water by gas chromatography and mass spectroscopy
نویسنده
چکیده
Phenol was analyzed by both gas chromatography–flame ionization detection (GC–FID) and gas chromatography–mass spectrometry (GC–MS) to compare the techniques and to find out if GCFID is a suitable tool for the analysis of phenol extracted from environmentally important phenol in water. After the treatment of water with CuSO4 and H3PO4, phenol in the water was extracted with dichloromethane. The extract was cleaned up by silica gel column chromatography. The analytical results obtained by GC-FID and GC-MS were generally of similar magnitude. Limits of detection and determination were between 0.01 and >0.05 ng/l and <0.01 and 0.05 ng/l, respectively. And the recovery of phenol was above 45%.
