Complexes of 3d and 4d elements with ethylenediamine and N,N '-ethylenediaminetetraacetic acid in catalytic reduction of silver halides in AgHlg-gelatin-immobilized matrix systems

The effect of 3d and 4d element complexes with ethylenediamine and N,N'-eth ylenediaminetetraacetic acid on the rate of AgHlg --> Ag redox process in t he preliminarily photoactivated matrices was studied. In the analysis of th is effect the most decisive is the energy of stabilization of given complex in the ligand field. The correlation of the degree of this effect and stab ilization energy was evaluated.
