Attainment of equilibrium verified by repetitive measurements. Aliquots of saturated solutions transferred through a course filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 372 nm. The International Union of Pure and Applied Chemistry Powell, J. R.; Voisinet, D.; Salazar, A.; Acree Jr., W. E.; Phys. Chem.
