Extractability of Copper and Application of Diffusive Gradients in Thin Films: Metal Availability in Contaminated Soil by Biosolids

Abstract

oxidizable > reducible > soluble. Biosolid application decreased of both soluble and reducible fractions and increased the amount of metal attached to the oxidizable fraction. Copper amount extracted by DGT from the soil solution was 13% of total metal in solution. In the case of soil, this amount was less than 0.3% of total metal. Furthermore, it was possible to directly relate the metal extracted by DGT with the available metal with CaCl2 or the metal bound to organic matter.]]>
