Recently a number of studies have shown that solvation effects and soil wetting are important in the sorption of organic pollutants to solid geosorbants. This study presents research that examines the role of water in the sorption of norflurazon to Pahokee peat and Elliot soil. The kinetics of norflurazon sorption was monitored over the period of 8 (or more) days in both an initially dry soil and a prehydrated geosorbant. Both the Pahokee peat and Elliot soil samples showed very different sorption kinetics depending on the hydration condition of the solid geosorbant. These results will be presented and discussed in relationship to recent NMR results from our group as well as in the literature. The role of the organic matter/mineral interface will also be discussed.
