Includes bibliographical references (page 13). "A number of refinery effluent and "produced water" samples were subjected to extraction by a variety of organic solvents of different polarities. These were then analyzed by GC/MS and GC/AEDV. The studies showed that acidification of the samples enhanced the extraction and reduced the difficulties caused by emulsions. Dichloromethane was the solvent of choice as it provided the most fine structure in the resulting chromatograms as well as providing optimum extraction capabilities as shown by the individual PAH and n-alkane concentrations. The complexity and response observed in the S-chromatograms of the effluent extracts indicate a large number of S-containing compounds present. Changes were noted in the S-chromatograms of the effluent during storage. The lack of reproducibility of the results of the extracts collected during the same sampling period suggests the heterogeneity of the effluent. The C chromatogram profiles were compared to the S and H chromatogram profiles and the O and P chromatograms were obtained"--Abstract.
