![عکس صفحه اول مقاله: Reduction of methylene blue by thiocyanate: Kinetic and thermodynamic aspects Reduction of methylene blue by thiocyanate: Kinetic and thermodynamic aspects](/preview/png/613315.png)
This article reports the reduction of methylene blue (MB) by thiocyanate ions (SCN−) in aqueous and micellar solutions. Thiocyanate ions are found to be an effective reducing agent for the decolorization of methylene blue under ambient condition. Effects of salting-in and salting-out agents have been investigated for real-time application in the reduction process. The salting-in agent urea has been found to uniquely enhance the rate of the reduction of MB by thiocyanate ion in the presence of micelles. Again, the catalytic activity of nanoparticles in the reduction of MB has also been studied. Detailed kinetic and thermodynamic aspects have been considered to realize the interaction between methylene blue and thiocyanate. Kinetic studies revealed that the reaction is reversible and follows first-order reaction kinetics.
