By determination of High Performance Liquid Chromatography (HPLC) capacity factors (k′), a comparison has been made of two new HPLC phases - physically and chemically immobilized humic acid - of their potential for determining soil adsorption coefficients (KOC) for organic pollutants. Log KOC values were estimated from log KOC versus log k′ calibration curves and were determined by using k′ and the humic acid content of the HPLC phases. These calculated log KOC values were compared with log KOC values taken from the literature.
