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 L Erlenmeyer flask with ground glass stopper and sidearm tap at base plugged and glass wool. The mixtures were agitated 12+ hr 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 salts for artificial seawater solution reagent grade.
- water: doubly distilled
Estimated Errors:
Ambient temperature: ±0.5°C
Mass concentration (m/v) (1): ±0.293 (95% confidence interval).

Experimental Values:
Note: The solubility of naphthalene in seawater is reported to be 22.0 mg/kg sln. The corresponding mass percent and mole fraction, x1, calculated by the compilers are 2.20 × 10-3 g(1)/100 g sln and 3.18 × 10-6.Graphical results for other salinities are also reported.
