Method/Apparatus/Procedure:
The samples were equilibrated in a thermostat bath with intermittent shaking over periods of 3-4 weeks. During the equilibration time, the pH values of the solutions were controlled by dropwise addition of phosphate buffer solution. The analysis of the solute concentration in the saturated samples was done spectrophotometrically either directly or by using proper colorizing agents.
Source and Purity of Materials:
- Probably a commercial reagent.
- Distilled water.
Estimated Errors:
Mass concentration (m/v) (1): <5% (evaluated on the basis of the reported results of the two techniques of analysis).
Components:
- Pentachlorophenol, $\ce{ C6HCl5O }$; [87-86-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
