Elution Mechanism of Fluorine from Steelmaking Slag into Seawater

Steelmaking slag contains nutrition such as Si, P and Fe and it is reported by our group that dissolved Si, P, Fe can accelerate phytoplankton growth by photosynthesis. Phytoplankton can fixate more carbon dioxide at unit earth surface area than any other creature on this planet. This means that by...

Description
Summary:Steelmaking slag contains nutrition such as Si, P and Fe and it is reported by our group that dissolved Si, P, Fe can accelerate phytoplankton growth by photosynthesis. Phytoplankton can fixate more carbon dioxide at unit earth surface area than any other creature on this planet. This means that by educing the potential of steelmaking slag, suppression of CO2 in the atmosphere and utilization of steelmaking slag can be achieved. In consideration of nutrition supply from steelmaking slag to seawater, we must avoid hazardous element dissolution from steelmaking slag into seawater. The elution mechanism of fluorine into the artificial seawater has been studied based on dissolution behavior of fluorine from synthesized fluorine containing substances into artificial seawater in the present work.
