Fig. 2. Copper breakthrough curves, representing Cu concentrations eluted in the centrifuge infiltration tests: (a) breakthrough of Cu as a single component (without competition), (b) breakthrough of Cu when in competition with Ni, and (c) breakthrough of Cu when in competition with Zn. The arrows signify the end of the infiltration of the metal solution, and the beginning of the desorption process.

Fig. 3. Nickel breakthrough, representing Ni concentrations eluted in the centrifuge infiltration tests: (a) breakthrough of Ni as a single component (without competition), (b) breakthrough of Ni when in competition with Cu, and (c) breakthrough of Ni when in competition with Zn. The arrows signify the end of the infiltration of the metal solution, and the beginning of the desorption process.

Fig. 5. Sorption isotherms for Cu, Ni, and Zn fitted with the Langmuir curve fit model. On the y axis S represents the equilibrium concentration of metal sorbed onto the soil solids, and on the x axis C represents the equilibrium concentration of metal remaining in the soil solution. Open squares represent the results from one of the replicate adsorption tests, closed squares the results from the other.
