Abstract
Batch adsorption studies have shown that sphagnum moss peat, which is essentially oligotrophic, in concentrations ranging from 4 to 40 g/l c an be used effectively to remove hexavalent chromium from aqueous solu tions. The process is pH dependent, the optimum range being 1.5-3. Tre atment of the exhausted peat with 1 M NaOH removed only 50% of the sor bed metal, suggesting that the binding to the peat involved strong che misorption forces.
