Description

The aim of this work was to evaluate the adsorption conditions of zinc and cadmium ions from aqueous solutions using a commercially available peat from Balneario Arroio do Silva, Santa Catarina State, Brazil. Adsorption studies were carried out in column experiments using radiotracers of the studied metals (65 Zn and 115 Cd). The pH influence and the interference of other ions, such as Na+, Ca2+, Fe3+ and Al3+ on the adsorption process were investigated. The results showed that peat columns are able to retain more than 99% of metal ions in solution in a range of pH from 3,7 to 6,5 Ca2'+ and Al3+ ions were the main interferent on adsorption of Zn and Cd ions in solution.
