Abstract: ADSORPTION OF ZINC AND CADMIUM ON PEAT COLUMNS.The aim of this work was to evaluate the adsorption conditions of zinc and cadmium ions from aqueous solutions using a comercially available peat from Balneário 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 + , Ca 2+ , Fe 3+ and Al 3+ 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.Ca 2+ and Al 3+ ions were the main interferent on adsorption of Zn and Cd ions in solution.
