VOLTAMMETRIC STUDY OF MESO-TETRA(p-SULPHONATE-PHENYL) PORPHYRIN(TPPS) AND ITS ZINK COMPLEX
Abstract:
In the solution of (0.4 mol KOH+0.6mol NH4Cl)/L PH=9.5 TPPS produces three po-larographic waves. The first step of reduction which involves 2H+ is a 2e reversible electrode process. Being coordinated with Zn(Ⅱ), the complex of ZnTPPS gave two reduction waves and one oxidation wave. The first reduction wave of ZnTPPS is reversible and involves one H+. Redunction of Zn2+ during or after the first reduction wave may result from the disso-ciation of ZnTPPS. The nearly equal strong adsorption of TPPS and ZnTPPS on Hg electrode was observed and Γ50,β0, K0 and G0 were cal culated.
