Removal of ‘soluble’ iron in the Potomac River estuary: Comments

Abstract

Eaton (1979) states that the removal of soluble Fe in the Potomac River estuary does not result from the coagulation of Fe-colloids by seawater cations but rather by the destabilizing action of “bacterial polymers’. The data of Eaton are used to demonstrate that the removal mechanism iss cation coagulation, the same process as observed in o'her estuaries.
