Investigating the persistence of iron-bound phosphorus in lake sediment under sulfidic conditions

Abstract Iron (Fe) additions are widely used to suppress internal phosphorus (P) loading in eutrophic lakes by promoting the formation of vivianite (Fe(II) 3 (PO 4 ) 2 ·8H 2 O), a redox-stable Fe–P mineral that can sequester P in anoxic sediments over the long term. However, vivi...
