Abstract
High performance reverse phase liquid chromatography (HPRPLC) retention parameters were correlated to organic-carbon-normalized partition coefficient ( K oc ) values for sorption of various uncharged organic substances onto sediments and soils in an attempt to devise a model for predicting sorption behavior. The results reveal a relationship between the logarithm of HPRPLC retention time and log K oc that appears to provide a reasonable means for estimating partitioning properties from HPRPLC data. The technique was compared to methods which utilize octanol/water partition coefficients ( K ow ) and aqueous solubilities as surrogate predictors of sorption behavior and was found to yield superior correlations in all cases tested.
