ABSTRACT:
A new process for the preparation of HO-EDTA.FE (5% Fe) is disclosed. It is based on the oxidation of Fe.degree. by nitric acid in the presence of HO-EDTA Na.sub.3 to generate the chelate in the Fe.sup.+2 state. The Fe.sup.+2 chelate is then converted to the desired Fe.sup.+3 chelate by air oxidation.
