Redox Kinetics and Mechanism of Malachite Green in Acidic Medium : Oxyanions oxidation of malachite green

Malachite green is a basic dye for wool, silk and for mordanted cotton. It is also widely used to dye materials such as jute, leather, ceramics and paper, in addition to being used as a cytochemical staining agent and has, in fact, been widely used as the most efficacious antifungal agent in the fish farming industry Its worldwide use in aquaculture will probably continue due to its relatively low cost, ready availability, and efficacy; therefore, potential human exposure to malachite green could result from the consumption of treated fish and from working in the dye and aquaculture industries. In spite of these applications not much kinetic data have been reported in literature. Relevant data on the kinetics of its reaction, especially with oxidizing agents would give an insight into the conditions best suitable for its reactions and the mechanisms of these reactions. Data generated in kinetic studies, especially in collaboration with data from toxicological studies and experts in fish diseases could be of importance in improving its uses, as well as its handling when used as an antimicrobial agent, as biological stain and in the dyeing industry
