Original Measurements
Eganhouse, R. P.; Calder, J. A.; Geochim. Cosmochim. Acta 1976, 40, 555-61.
Variables:
Ambient temperature: 25.0 °C
Salinity: 35 g/kg sln
Prepared by:
Method/Apparatus/Procedure:
Equilibrium flask: 1-dm3 Erlenmeyer flask with ground glass stopper and sidearm tap at base plugged with glass wool. The mixtures were agitated 12+ hrs at 215 rpm on a New Brunswick gyrotary shaker; a 24 hr stationary equilibrium period followed. Hydrocarbons were extracted with doubly-distilled hexane 3 times; concentrated by evaporation, with losses checked against an internal standard. Analysis: gas chromatography.
Source and Purity of Materials:
- Analytical grade salt for artificial seawater solution, reagent grade. Water: doubly distilled.
Estimated Errors:
Ambient temperature: ±0.5°C
Mass concentration (m/v) (1): ±0.025 (95% confidence interval)

Experimental Values:
Note: The solubility of phenanthrene in seawater is reported to be 0.71 mg/kg the corresponding mass percent and mole fraction, x1, calculated by the compilers are 7.1 × 10-5 g(1)/100 g sln and 7.4 × 10-8.Graphical results for other salinities are also reported.
