摘要:

The adsorption of Cd and Cu by three different soils was studied in the presence of variable concentrations of calcium chloride. Cadmium adsorption fitted the Freundlich equation while Cu better fitted the Langmuir equation. Increasing ionic strength decreased metal adsorption because of the competition of Ca‐ions for the adsorption sites of the soils.
