ABSTRACT:
Degradation of thionine (Th) was observed with UV/visible spectrophotometer at λmax 599 nm using maltose as a reductant in aerobic conditions. A significant role of ionic strength by changing the concentration of nitrate ions was observed, leading to more rapid degradation of dye at increasing concentration than low concentration, which was confirmed by measuring the optical density of the reaction mixture. Rate constant at elevated temperature showed that reaction depends upon ionic strength and temperature that follows pseudo-first-order kinetics. Activation parameters like Ea , ΔG*, ΔS* and ΔH* were computed, and a mechanism of reduction of dye was proposed.
