Adsorption/Desorption Isotherms of Hg(II) by Soil

Abstract
The processes of adsorption and desorption of Hg(II) by 15 soils were investigated. Within an initial Hg solution concentration range of 1.0 × 10-7 to 1.1 × 10-4M, all soils with a large organic matter content (> 11.0 g C kg-1) had an S-type isotherm, whereas all soils with a low organic matter content (
