Hematoxylin is extracted from the Central American logwood tree; the dye is classified as a flavone or pigment. A comprehensive review on the chemistry, application and extraction of hematoxylin has been published by Puchtler et al. [1]. Hematoxylin is one of the oldest dyes used in histochemistry. In this work, electrochemical behavior of Hamatoxylin [2] in the presence of AlCl3 and H3BO3 has been studied then synthesis of haemalum in the presence of hematoxylin, potassium iodate (oxidizing), distilled water and etc [3]. Upon oxidation, hematoxylin changes color from yellow to dark blue. The electrochemical behaviour of haemalum in the presence of Phosphate and EDTA has been studied using cyclic voltametry as a diagnostic technique. The results indicate that this system is involved in the CE process. CE is an infrequently observed mechanism with individual I - E curves, and it contains a preceding chemical reaction for the production of electroactive species.
