Variables:
Room Temp:
25
°C
Salinity:
29 - 108 g(2)/kg sln
Prepared by:
Method/Apparatus/Procedure:
Saturated solutions were prepared by adding excess [1] to a previously prepared salt solution. The resulting mixture was stirred for 24 hours and then allowed to settle for 48 hours. An aliquot was extracted with cyclohexane which was then analyzed spectrofluorometrically.
Source and Purity of Materials:
- Fluorescence grade, from Eastman Kodak.
- Reagent grade, from Fisher Scientific.
Estimated Errors:
Ambient temperature: ±0.5°C
Mass concentration (m/v) (1): ±3 relative%
