Synchronous Treatment of Heavy Metal Ions and Nitrate by Zero-valent Iron
零价铁对重金属和硝酸根的同步去除研究

The wastewater which contains bivalent copper and nitrate,bivalent nickel and nitrate,hexavalent chromium and nitrate were simultaneously treated by the zero-valent iron(Fe~0) system to investigate the feasibility of using Fe~0 for the remediation of contaminated groundwater.The experimental results indicate that nitrate has no obvious effect on the removal of heavy metals,and different heavy metal has different impacts on the removal of nitrate.Bivalent copper accelerates the nitrate removal percentage and...
