摘要：
By determination of HPLC capacity factors (k′) for a series of aromatics it has been possible to determine the soil adsorption coefficients (Koc). The effect of column type and mobile phase composition on the correlation between log Koc 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 Koc 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. © 1990.
