Method/Apparatus/Procedure:
Details given in reference [1]. Saturated solutions were prepared by equilibrating excess naphthalene and salt solution in an ampoule with shaking for 24 hours. The filtered saturated solution was analyzed by a UV Spectrophotometer.
Source and Purity of Materials:
- Naphthalene: 99.99+% from james Hinton, Valparaiso, Florida
Salts: Analytical reagent grade from Mallinckrodt
Natural Seawater: collected at West Falmouth, Buzzards Bay, Quicks Hole and Mashapaquit Creek, Massachusetts
Estimated Errors:
Ambient temperature: ±0.03°C (authors)
Mass concentration (m/v) (1): ±3% (authors)
