Soil partition coefficients for Cd by column desorption and comparison to batch adsorption measurements
Article Abstract:
A new technique for associating the batch adsorption and column desorption behavior of cadmium on soils was evaluated. The method determines contaminant desorption from a series of columns as a function of water flow through the column. Either a linear or exponential extrapolation is then used to determine the concentration of each flow. It is shown that there is a linear relationship between the desorption partition coefficients and the corresponding adsorption coefficients.

Predicting soil-water partition coefficients for cadmium
Article Abstract:
The adsorption of Cd(II) was analyzed by adsorption isotherm and adsorption edge measurements of 15 soil samples collected from different sites in New Jersey. Adsorption isotherm and adsorption edge measurements indicated the pH-dependent adsorption of Cd(II) in 15 soil samples representing the different soil types of New Jersey. Furthermore, the diffusion of Cd(II) from the different soil types was affected by the amount of organic matter in the soil.

Chemical interactions between Cr(VI) and hydrous concrete particles
Article Abstract:
The chemical interactions between Cr(VI) and concrete particles in synthetic groundwater were investigated. There were three main reactions observed at the concrete-water interface: redox, adsorption and precipitation. The results showed that the pH of the solution was an influential parameter which helped to determine chromium reaction behavior with hydrous concrete particles.
