Název v původním jazyce

A model experiment: competitive sorption of Cd, Cu, Pb and Zn by three different soils

Popis výsledku v původním jazyce

The aim of this study was to evaluate and compare the competitive and individual sorption of Cd, Cu, Pb and Zn on three natural soils: a Gleyic Fluvisol (content of Cd 30, Cu 25, Pb 2297 and Zn 3718 mg/kg), a Gleyic Cambisol (content of Cd 5, Cu 29, Pb 1158 and Zn 180 mg/kg) and a Chernozem (content of Cd 0.4, Cu 36, Pb 75 and Zn 67 mg/kg). For evaluation of the sorption and desorption, the Freundlich isotherms were used. The results of the model experiment confirmed that the sorption from single-metalsolution was more effective than sorption under multi-metal conditions, due to competitive effects. In all tested soils sorption of Cd, Cu and Zn decreased with the rate of other competitive metals; the Pb sorption was not affected by other competitive metals in solutions. In general, sorptions of Cu, Pb and Zn were greater in uncontaminated soil compared to contaminated soils. The results showed the sorption decreasing in order Chernozem > Fluvisol > Cambisol.
