Název v původním jazyce

Coupled ICP-AES-SEC study of Pb and Zn complexation in long-term contaminated soil

Popis výsledku v původním jazyce

The complexation and mobilization potential of Pb and Zn by humic acids (HA) from soil and brown coal was tested in soils from long-term contaminated and non-contaminated sites close to a lead smelter. The molecular weight distribution of HA was evaluated by HPLC-SEC. HA from Leonardite showed a lower apparent molecular weight (MW) in comparison to HA extracted from arable and grassland soils. The capacity of heavy metal complexation by HA fractions of different molecular weights was evaluated by meansof coupled ICP-AES-SEC. HA originating from brown coal complexed Zn better than the autoctonous HA. Molecular weights fractions relevant for metal-complexing were found in the range of 2.5-5.0 kDa where HA of brown coal exhibited their major binding capacity. HA of grassland soil moderately complexed Zn, whereas HA of the arable contaminated soil showed only a small ability to complex Zn. HA strongly complexed Pb, particularly the HA of grassland soil whose complexing ability exceeded ev
