Description:
A synthesized Mn mineral used in study on adsorption of heavy metals from water has shown a great adsorption capability for Pb, Cu, Cd, Co, Ni and Zn on this mineral over a pH range from 2 to 8. The retention of Pb on this mineral was as high as 10% of its weight. Application of this mineral into soils at the rate of 1% increased metal adsorption capability of the mixture by 5 times, indicating that addition of this mineral in soils altered the chemistry in soils. This Mn mineral became the dominate component in controlling solution concentration of heavy metals. Results from this study demonstrate a potential use of this mineral to immobilize heavy metals in soil/water systems.
