Abstract

By determination of HPLC capacity factors (k′) for a series of aromatics it has been possible to determine the soil adsorption coefficients (K_oc). The effect of column type and mobile phase composition on the correlation between log K_oc and log k′ has also been studied. We have prepared a new HPLC packing material which bears immobilized humic acid and from the values for K_oc it appears this new HPLC phase is superior to other procedures - partition into n-octanol and retention on HPLC silica-based phases - which have been used to model the sorption of aromatic substances on soil or sediment.
