Abstract

Chitin

Chitosan

Manganese(VI)

Oxidation

Permanganate

Polysaccharides

The formation of a short-lived manganate(VI) intermediate has been confirmed during the oxidation of chitin and chitosan polysaccharides by the permanganate ion at pH's ≥ 12, spectrophotometrically. The Mn(VI) transient species intermediate was characterized by a band at a wavelength of 610 nm, an absorption maximum, with a absorptivity (i.e., molar extinction coefficient) of 1250 ± 75 dm 3 mol −1 cm −1 .
