Abstract

Fine sludge’s were collected from five filtration plants, and the partitioning of ten metals (Ag, Cd, Mn, Zn, Pb, Cu, Sn, Co, Ni and Fe) anthem was determined by selective leaching techniques.



  1. The available amounts, which shows the total of each metal leached between 1 M. CH3COONH4 and 30percent H2O2, for Ag, Cd. and Mn, ranged from 51 to 98 percent for five sludge’s.

  2. The available amounts for Zn, Pb, Cu and Sn were 47 - 92 percent for five sludge’s.

  3. The most important fraction for Co, Ni and Fe, except the Ueckermünde sludge, which is markedly polluted by organic matter, was the crystalline particle.

  4. Therefore, the above metals, except Co, Ni and Fe, are thought to be enriched on ion exchangeable sites, organic matter, hydrous Fe/Mn oxides and sulphides in fine sludges.
