Solubilization of Zn, Cu, Mn and Fe from a river sediment by olive mill wastewater: Influence of Cu or Zn
The solubilization of Zn, Cu, Mn and Fe from a river sediment by wastewater from olive mill (WOM) in the presence of a given initial concentration of Cu or Zn was studied. The presence of Zn does not affect significantly the solubilization of the metals. When Cu is initially present, the WOM capacity for solubilizing this metal is limited and always below the amount initially present, 5 mg L-1, and the amounts of Fe extracted are about half those previously found in the absence of Cu. Solubilization of Zn and Mn are not affected by the presence of Cu. The behaviour of Cu and Zn was modelled assuming the formation of a simple mononuclear-bidentate complex. More than 90 per cent of the variance is explained by the model for Cu. with a stability constant of 3×103. Zn gives a less satisfactory fit, probably because not all the available ligands form complexes with this metal.
