An assessment of cadmium availability in cadmium-contaminated soils using isotope exchange kinetics
(Soil Science Society of America, 2004)
There has been much research conducted to find suitable methods for the determination of available Cd in soils. In recent years, an isotope exchange kinetics (IEK) technique has been tested to describe the kinetic transfer ...
Kinetics of cadmium and cobalt desorption from iron and manganese oxides
(Soil Science Society of America, 1995)
Oxides of Fe and Mn in soils are capable of sorbing large amounts of trace metal ions and can therefore be important in controlling trace metal concentrations in soil solution, and hence trace metal bioavailability in ...
Cadmium and cobalt desorption kinetics from soil clays: effect of sorption period
(Soil Science Society of America, 1998)
Soil solution metal concentrations and hence metal bioavailability are controlled by sorption-desorption reactions at the surfaces of soil colloids. Compared with the numerous studies on sorption of metals by soils, there ...
A laboratory study of bacteria-facilitated cadmium transport in alluvial gravel aquifer media
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Colloids, including bacteria, can dramatically accelerate the transport of heavy metals in ground water. Batch and column experiments were conducted to investigate adsorption of cadmium (Cd) onto Bacillus subtilis spores ...
