| Abstract | ||
| The present work aims to study the effect of some soil properties on specifically adsorbed zinc in some soils of Egypt. Therefore , surface and subsurface soil samples with different physico – chemical characteristics were selected from different location. The result showed that the adsorption zinc correlated positively with all of clay +silt content, pH, calcium carbonate and cation exchange capacity. The data indicated that the adsorption Zn increased with increasing (pH) and increased with increasing the concentration of Zn added in solution. Zinc desorption decreased as the pH values increased. | ||
