Immobilization of Cr6+ in soil as using a mixed soil by inside adsorption

摘要

Generally, landlocked bodies of water and wetlands advance environmental pollution including eutrophication and heavy metal sedimentation. It has a influence for ecosystem and using of water. In a river of an inner city, there is a river maintained top and bottom style by opening and shutting of a water gate, and change of these rivers, eutrophication and environmental pollution by heavy metal are studied in particular. hi this study, we focused on the quality of bottom soil as mechanism of water environment in these rivers (It said staying river at here) and environmental pollution by heavy metal. We have dissolves phenomenon of Cr6+ particularly and examined insolubilization measures procedures in this study.
