摘要：

The chemical and physical characterization of coastal peat has been studied. It was examined the pH, organic matter content:and elementary and XRD analyses, among other characteristics. The peat was then applied to the retention and competition of metal micronutrients (Cu and Zn) from metal nitrate solutions. The retention was affected by both the pH and time of adsorption, while the competitive character of these metals for the substrate was relevant to each pH examined.
