Examination of silica-salicylic acid and silica-8-hydroxyquinoline HPLC stationary phases for estimation of the adsorption coefficient of soil for some aromatic hydrocarbons

As part of the development of a liquid chromatographic procedure for predicting the environmental fate of organic pollutants, we have evaluated silica-derivatized stationary phases as models for the organic constituents of soils. These silica-derivatized phases, formed by immobilizing salicylic acid and 8-hydroxyquinoline on silica, have been evaluated by estimating the soil partition coefficients (Koc) for a series of organic chemicals and comparing them with values reported in the literature.
