Abstract
Soil organic matter influence on Langmuir isotherms for Cu and Cd in four Italian soils of different pedogenetic origin was investigated. Adsorption processes were carried out either on the whole soils or on soils after destruction of organic matter. Organic matter removal produced a noteworthy decrease of Cu adsorption contrasted by a smaller decrease or even a slight increase of Cd adsorption. Addition of increasing amounts of Cu on soil previously enriched with Cd did not significantly change the Cu adsorption while a rather different pattern was observed when increasing quantities of Cd were adsorbed on the same soil after Cu enrichment. In this case Cu already present in the soil reduced the amount of Cd adsorbed. These findings suggest that the differences found in the adsorption process of such metals primarily depend on the different chelating effectiveness of soil organic matter in the respect to Cu and Cd.
