Abstract

LAMIM, Agenor Paulo Binato; JORDAO, Cláudio Pereira; PEREIRA, José Luis  and  BELLATO, Carlos Roberto. Chemical and physical characterization of coastal peat and evaluation of competitive adsorption of copper and zinc. Quím. Nova [online]. 2001, vol.24, n.1, pp.18-23. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422001000100005.

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.

Keywords : heavy metals; coastal peat; copper and zinc competition.
