THE EFFECT OF OXYGEN ON THE INCORPORATION OF MANGANESE,IRON AND COBALT INTO HEMATOPORPHYRIN IX IN GLACIAL ACETIC ACID

Abstract

The results of polarography studies for the reaction of hematoporphyrin IX with Mn(II), Fe(II) and Co(II) ion in acetic acid in the absence and the presence of oxygen are reported. The metal incorporation reaction in the presence of oxygen is quantitative for Mn and Co and incomplete for Fe. In the absence of oxygen, the Mn reaction does not proceed at all, whereas, both the Fe and Co reactions are quantitative.
