黄河表层沉积物对Hg^(2+)的吸附研究

Adsorption of Surface Sediment in the Yellow River on Hg^(2+)

通过大量的实验工作,较为全面地探讨了黄河表层沉积物对重金属Hg2+的吸附、解吸特性,提出了黄河表层沉积物对Hg2+的吸附等温线。另外,还探讨了pH、泥沙浓度、温度、矿化度对Hg2+吸附等温线的影响。

In this paper, the adsorption and desorption characteristics of surface sediments in the Yellow River on Hg2+are measured by a mount of experiments, a kind of the adsorption isotherm of the sediment on Hg2+, Furthermore, the effects of pH, temperature, sediment concentration and total salts contents onthe adsorption isotherms of Hg2+ were evaluated.
