In the present work,The oxidation behavior of the natural polymer "pectin" was examined using potassium permanganate as a strong oxidizing agentvia cyclic voltammetryin KCl aqueous solution. A pair of waves was given, as the pectin was oxidized by the permanganate that was reduced, and upon studying a relationship between some physical parameters over time:it was found that most of the reactions follows two steps, the first step is fast, which supports the occurrence of oxidation, and the second is slow, where a complex is formed between permanganate and pectin and their data were discussed.
