Abstract
Upon cyclic electrochemical polarization, traces of 5, 10, 15, 20-tetraphen yl-21H, 23H-porphyrin(H2TPP), which have been mechanically transferred to t he surface of a paraffin-impregnated graphite electrode, can incorporate co pper, iron or cobalt ions from aqueous solution into the porphyrin ring to form CuTPP, FeTPPCl and CoTPPCl, The binding of metal ions by H2TPP can be studied by voltammetry of immobilized microparticles. The mechanism of form ation and reaction of the metalloporphyrins and their electrocatalytic prop erties were elucidated.
