... are made by combining information from field measurements (boreholes, soundings, etc) with knowledge of the geological history of the area. The geological models are translated into contaminant migration models by adding parameters that are important for contaminant transport, such as adsorption and rate...

... ABSTRACT: This paper presents a study of metal adsorption by a Brazilian vermiculite, and a critical analysis of some aspects of the adsorption test procedure. Current or potential geo-environmental uses of vermiculite associated to its high ion exchange capacity include treatment...

... adsorption techniques. This paper assesses a correlation between the adsorption of methylene blue, and a measure of the expansive potential of a clay soil: the shrink swell index. It is found that by adopting a streamlined titration technique, methylene blue adsorption values can be obtained quickly...
