Removal of Iron in Nickel Precipitation Residue Wastewater with Magnesium Oxide

Abstract:

The wastewater with iron is a threat to health of human and environment. MgO was used to remove iron and the effect of MgO added amount, the reaction time and temperature on the removal of iron ion were investigated. The removal rate of iron ion was more than 99% and the optimal added amount of MgO was 2.5 g/L with reaction time for 40 min at 25 oC. The results of study on the use of MgO as a water treatment reagent to treat wastewater containing iron ion indicated that MgO had an excellent performance to treat wastewater with iron.
