Abstract:The current research achievements and status of applying nanoscale iron on water
treatment are iron can remove heavy metals,anic anions,nuclear pollu-
tants and anic pollutants effectively from water,and the removal efficiency is affect-
ed by initial concentration of pollutant,nanoscale iron dosage,pH,reaction time and other factors.
Due to the strong reduction ability and instability of nanoscale iron,its practical application has been
limited,and it is necessary to develop modified on the domestic and international
research development,this paper analyzed the remove efficient and mechanisms of nanoscale iron
modified materials and discussed the prospect of the its application in water treatment industry.
Keywords:Nanoscale iron
