Abstract
IN 1952, Jones and Long1 observed that the iron (III) ethylenediamine tetraacetate complex is photosensitive. Hill-Cottingham2 also noted the photochemical dissociation of this complex, which he applied for qualitative work in his investigation of the photochemical dissociation of iron (III) chelates by the action of daylight, Weinstein, Robbins and Perkins3 examined this complex at pH 7; they remarked that it is more stable than other metal ethylenediamine tetraacetate complexes over a wide pH region. They suggested that it is metabolized in the plant. Heath and Clark have studied the iron supply of plants by using this complex4.
