Role of cationic gemini surfactants (m-s-m type) on the oxidation of d-glucose by permanganate

Cationic gemini (m-s-m type; m = 16, s = 4,5,6) surfactants were used to determine the micelles assisted kinetics parameters, mechanism of permanganate-D-glucose redox system in an aqueous solution by means of UV-visible spectroscopy at 40 °C. Effects of different [gemini surfactant], [permanganate]...
