Determining total oil and grease content in wastewater by solid-phase extraction
- Tennessee Technological Univ., Cookeville, TN (United States)
Standard protocol for the determination of oil and grease in industrial and municipal wastewater currently utilizes chlorofluorocarbons (Freons{trademark}) for liquid-liquid extraction. Environmental concern for stratospheric ozone depletion has prompted investigation into alternative methods. EnvirElut{trademark} solid-phase extraction (SPE) columns were developed and evaluated for this analysis. The recovery and variability determined for synthetic samples, fortified with vegetable or used motor oils, were comparable to that expected by liquid-liquid extraction. This presentation reports the results obtained upon comparison of the recovery observed for oil and grease analysis of industrial and municipal wastewater by solid-phase extraction to conventional liquid-liquid extraction procedures using Freon{trademark} 113. Various means of introducing the sample to the solid-phase extraction column, sample elution solvents, and sample drying procedures are explored.
