Soil Adsorption / Mobility

An experimental Koc of 50 has been reported for acrylamide(1). According to a classification scheme(2), this Koc value suggests that acetamide is expected to have very high to high mobility in soil. No significant adsorption of acrylamide by natural sediments, industrial and sewage sludges, clays (montmorillonite and kaolinite) was observed in adsorption studies(3). In an experiment evaluating leaching using soil TLC (thin-layer chromatography), Rf values ranging from 0.64 to 0.88, measured on four soils, indicated acrylamide is mobile in soil(4). Acrylamide has a higher mobility in sandy soils than in clay soils(4,5).
