Sediment-column experiments, soil sorption

Soil sorption is an important detoxification process for pollutants of aquifer waters however, sediment-column experiments to determine the soil sorption capacity are tedious, expensive and their results are affected by various extraneous factors. It was proposed to estimate the adsorption coefficients KA based on their correlation with the capacity factors, k, measured by isocratic RP-HPLC108. A QSAR estimation study was carried out of soil sorption coefficients, K0c, of polar organic chemicals such as substituted anilines and phenols, based on descriptors such as n-octanol-water partition coefficients, Kow,...
