Abstract

Zinc can be added to the soils through disposal of city wastes, sewage sludge and a variety of agricultural practices. Its availability to plants, persistency and mobility in soils are mainly determined by the extent of the adsorption by soil particles. Considering the importance of Zinc to the plants and soil contamination, a study was conducted to obtain the quantitative relationship between the Zn in the equilibrium solution and that adsorbed by the Camara Watershed Cambisols, on the Paraiba State and to evaluate the thermodynamic parameters involved in the adsorption process. Adsorption isotherms were elaborated from batch adsorption experiments, with increasing Zn concentrations. The driving force of reaction was quantified by Gibbs free energy and a separation factor. Isotherms were H and L-type and the experimental results well fitted to Langmuir model. Zinc adsorption was favorable and spontaneous depending on organic carbon content and, mainly, on the cation exchange capacity of the soil. Free energy adsorption was higher at lower zinc equilibrium concentrations.
