heavy metal - Opis:
- Model research on competitive sorption of heavy metal cations (Cu2+ , Zn2+ , Ni2+ ,Co2+ , Cd2+ and Cr3+ ) with Ph2+cations was carried out in the followingmineral soils: grey-brown podzolic derived from loess (Orthic Luvisols)using a dynamic method.Investigation on the course and the range of the sorption from the two- component solutions allowed to determine mobility of individual heavy metal cations in relation to lead (II) cations.At the same time, it allowed to evaluate their phyto-availability. Elements, which most easily entered sorptive complexes of both of the investigated soils were copper (II) and chrominium (III) cations. The rest of the cations showed different energy levels of entrance with simultaneous sorption with lead (II) cations. During competitive sorption of heavy metal cations, i.e. at saturation the columns with two component solution, the presence of the second, opposite process namely desorption of the following cations from the soil:Co2+ , Zn2+ , Ni2+ , and Cd2+ was observed. Desorption levels were characteristic for particular cations and depended on the type of soil.
