The complexation of Hg(II) with soil-derived humic substances was investigated using an iodide selective electrode. Humic substances were titrated with Hg(II) at fixed pH values, 4, 5, and 6. The binding behavior was successfully described with a con

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 isothe
