Voltammetric measurements at the surface of cotton: absorption and catalase reactivity of a dinuclear manganese complex.

Voltammetric measurements at the surface of cotton fabric were conducted after impregnating the surface of the textile with graphite flakes. The resulting conducting surface contact was connected to a conventional basal plane pyrolytic graphite substrate electrode and employed both in stagnant solution and in rotating disc voltammetry mode. Diffusion through the immobilized cotton sample (inter-fiber) is probed with the aqueous Fe(CN)6(4-/3-) redox system.
