The reactivity of Na and salt of oxidized cellulose and its oligosaccharides with chitosan will be presented. Hydrolysis of Na and salts of oxidized cellulose was carried out in homogenous system by means with microwave irradiation at constant conditions. The reaction progress was monitored by capillary isotachophoresis and size exclusion chromatography. Reactivity of oxidized cellulose or its hydrolysates with NH2 groups of chitosan was promoted by MW irradiation. Reaction was monitored by infrared spectroscopy.

Deriváty oxidované celulozy s chitozanem byly připraveny za mikrovlnného ohřevu a byly sledovány kapalinovou chromatografii.
