Methodology:
Constant temperature bath, centrifuge, thermometer, and a spectrofluorimeter. Solubility determined indirectly from measured aqueous solubility and solute partition coefficient between n-heptane and water. Solute concentration in both phases, after equilibration and centrifugation, determined from the fluorescence intensity. This indirect method computes the solubility that is expected assuming that the dilute solution behavior extrapolates up to saturation point.
Sample Information:
