The objective of this work was to study the removal of dissolved metals from industrial effluents. The sorption of Cu, Zn, Cr, Pb, Ni and Cd from multicomponent mixtures was studied in a flow-through column packed with different sorbents. The materials studied were peat, two types of tree bark, rock wool and wood fibers made of reclaimed (recycled) paper. The metal-coating waste waters were collected from several industrial plants representing different industrial sectors in Finland. This research demonstrates the easily available materials can be used to remove dissolved heavy metals from industrial effluents. At very hogh metal ion concentrations the system seems to be inadequate, therefore the main purpose could be polishing of conventionally treated effluents.
