摘要
From measured breakthrough curves of sorbing chemicals in local equilibrium, one can obtain the entire nonlinear adsorption isotherm by a simple integration. The feasibility of the procedure is demonstrated by comparing nonlinear adsorption isotherms obtained from column experiments with batch studies for sorption of a heavy metal and an organic cation on sand. The advantages and drawbacks of this technique for the measurement of isotherms on materials of environmental origin are discussed.
