Removal of Manganese(II) Ions from Wastewater by H₂O₂as Oxidant

Abstract:

Removal of manganese (II) ions from wastewater by H₂O₂as oxidant was studied. Effects of reaction temperature, hydrogen peroxide concentration, reaction time and calcium oxide concen-tration on the manganese removal were investigated. The results indicated that the removal rate of manganese exceeded 99.9% and the Mn (II) ions concentration of treated wastewater was lower than 0.1 mg·L^-1 under the conditions of reaction temperature 55 °C, concentration of H₂O₂0.1 mL·L^-1, reaction time 70 min, concentration of CaO 0.25 g·L^-1.
