Method/Apparatus/Procedure:
Two methods were used.
At 25 °C the solubility of (1) in (2) was determined from UV absorption measurements and was used as a standard at other temperatures. At other temperatures the spectrofluorimetry method was used.
The sealed fluorescence cells contained 5 mL of the aqueous solution and an excess of (1) were rotated at least 72 h in a water bath, then removed, quickly wiped dry and placed in the fluorimeter.
Source and Purity of Materials:
- Source not specified; better than 99 mole%, by glc; used as received.
- Distilled over $\ce{KMnO4}$ and $\ce{NaOH}$ and passed through a Sephadex column.
Estimated Errors:
Ambient temperature: ±0.1°C
Mass concentration (m/v) (1): see above
Components:
- Phenanthrene, $\ce{ C14H10 }$; [85-01-8] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
