            Batch sorption tests were conducted to investigate the sorption 
            capacity of organic compounds by ground tire and to assess the 
            effects of the presence of other organic compounds, ionic strength, 
            pH, ground tire particle size, and temperature on sorption. None of 
            the factors were significant under the conditions tested. m-Xylene 
            had the highest partition coefficient (977 L/kg), followed by 
            ethylbenzene, toluene, trichloroethylene, 1,1,1-trichloroethane, 
            chloroform, and methylene chloride (13 L/kg). The partition 
            coefficients had a logarithmic linear relationship with the 
            octanol-water partition coefficients. The diffusion coefficients of 
            the compounds tested were in the range of [10.sup.-8] [cm.sup.2]/s. 
            The diffusion coefficients did not correlate well with the 
            physical/chemical properties, such as molecular size, of the 
            compounds tested. The heat of solutions of the compounds tested had 
            relatively low values (<2.5 kJ/mol/K). Thus, the sorption may not be 
            affected significantly by temperature change. Organic compounds 
            sorbed onto tire rubber appear to be sorbed primarily onto tire 
            rubber polymeric materials and partially carbon black in the tire 
            rubber. Overall, ground tire shows significant capacity as a sorbent 
            of organic compounds.
