Abstract

Two novel stationary phases have been prepared by immobilizing humic acid on aminopropylsilica and alumina and used to study, by reverse-phased high performance liquid chromatography (RP-HPLC), the contribution of the mineral phase upon the sorptive properties of soil humates for organic pollutants. By determination of Koc, the adsorption coefficient for the organic carbon of soil, for a series of aromatic hydrocarbons it has been shown that the mineral phase has little influence upon their sorption by humic acid, the principal organic component of soil.
