Recent strategies for the removal of iron from water: A …
Methods such as ion exchange, supercritical fluid extraction, adsorption, wetland treatment, aeration and sequestration were less effective in the removal of iron from the water samples. Their iron removal efficiency was in the range of 40–80%. The iron removal method involving Vyredox technology exhibited lowest iron removal efficiency (3.12%).
