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 ...
Fractionation and distribution of arsenic in soils contaminated by cattle dip
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 1998)
Soils surrounding cattle dips in Australia are known to be highly contaminated with As and are potentially of major concern to the environment and human health. A study of 11 dip sites in northern New South Wales (NSW) has ...
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 ...
Desorption of copper from some New Zealand soils
(Soil Science Society of America, 1993)
Availability of soil Cu to plants is dependent on the desorption into the soil solution of Cu from the surfaces of soil colloidal materials. Although there have been many studies of Cu sorption by soils, however, few have ...
Application of capillary electrophoresis to anion speciation in soil water extracts: II. Arsenic
(Soil Science Society of America, 2000)
A method has been developed for the speciation of arsenic (AsO₂⁻, AsO₄³⁻, and dimethylarsinic [DMA]) in natural soil solutions from contaminated sites in Australia. The separation of these anions was achieved by capillary ...
