Removal of As(V) from water using galvanically coupled sacrificial metals.

The Permeable reactive barriers (PRBs) is one of the sustainable methods of environmental remediation for groundwater treatment. On using iron as reactive media for PRBs, the longevity of the column is affected by the accumulation of iron corrosion products resulting in permeability reduction. Hence, in this work, iron and zinc are employed as sacrificial metals to remove 50 mg/L As(V) from aqueous solution in an oxic environment, where copper is added as a noble metal.
