The Influence of Low- and High-Molecular Chelating Additives upon the Reduction of Nitrotetrazolium Blue to Formazane in the Presence of d-Metal Cations

摘要

The influence of high- and low-molecular additives upon the reduction of nitrotetrazolium blue to formazane in the presence of d-metal cations was studied. It was shown that the introduction of chelating additives did not essentially change the earlier found regularities in the variation of anti- and prooxidant activity within the range of d-metal cations. In most cases the observed effects may be understood in the terms of the theory of hard and soft acids and bases.
