A contaminated groundwater contains 100 g/L each of chloroform, trichloroethene, and tetrachlorethene. Calculate the equilibrium concentration (in mg/g) of each compound on activated carbon if the Freundlich isotherm K value for each compound is as given in Table 10-4 and the 1/n value is assumed to be 0.45 for the following conditions (a) assuming each is the only contaminant present in the groundwater (single-solute adsorption) and (b) that all three are present in the groundwater simultaneously (multicomponent adsorption). Calculate the solid-phase concentration of each under multicomponent adsorption conditions as a percentage of its solidphase concentration under single-solute adsorption conditions. How is the solid-phase concentration of each affected by the presence of other compounds? What in the impact of the value of K with regard to the effect of competition from other solutes?
