Estimation of water solubility and octanol/water partition coefficient of hydrophobic dyes: Part II: Reverse-phase high performance liquid chromatography

摘要: Abstract Capacity factors were determined for 20 disperse and solvent dyes by a high performance liquid Chromatographic method using methanol/water C-18 reverse-phase column. Regression equations are given that establish relationships among capacity factors, water solubilities octanol/water partition coefficients. The is easy to apply commercial with resulting estimations accurate better than one order of magnitude. Possible sources error discussed suggested as implicit in the when applied dyes. regressions also used estimate coefficients 14 other indigo, none which have been previously measured. estimated values all correspond calculated sediment I bioconcentration ranging from about 2.3 8.5 2 7 log units, respectively.
