【Abstract】 The removing efficiency of arsenic from high arsenic groundwater by using mixed iron powder and quartz sand has been studied. The effect of mass ratio of iron powder and quartz sand on the removal efficiency of arsenic has been investigated. It shows that arsenic in groundwater containing high arsenic can be removed efficiently, when the filling ratio of m(iron powder)∶m(quartz sands)=2.0∶100. The mass concentration of arsenic in the effluent water can be lower than 50 μg/L. The method is economic, highly efficient and highly promising.更多还原
