Iron filings or zero-valent iron (ZVI) is the elemental form of iron with a zero charge carried by each atom – a result of the outer valence level being filled. ZVI is able to remove phosphate from solution through precipitation. <ref name=Rossetti>Rossetti M. Evaluation of phosphorous removals by biochar supported nano-scale zero-valent iron. 2017.
