Capillary gas chromatographic analyses of the petroleum hydrocarbons in coastal seawater
- 24 Downloads
This study of the petroleum hydrocarbons in coastal seawater, using dichloromethane extraction with O-terphenyl and n-C20 as internal standards, and gas chromatography with silica-capillary-column showed that the recovery of petroleum hydrocarbons reaches 87.8% and that the lowest detection limit is 0.96 μg. This method is reproducible, highly accurate, and applicable for determining the petroleum hydrocarbons in coastal seawater.
