## Abstract The rate of demetallation of α, β, γ,δ‐tetra(__p__‐sulfophenyl)porphineiron (III), Fe(TPPS)^3‐^, was determined in sulfuric acid‐ethanol‐water media for 8.5‐10.65__M__ sulfuric acid at different temperatures. The overall reaction was the conversion of the complex Fe(TPPS)^3‐^ into the d
