Fig. 3. Influence of different lignin content of the raw materials on the aldehyde groups content during the periodate oxidation. The reaction conditions were kept constant in all experiments at 75 °C and 3 h. DACp corresponds to dialdehyde cellulose obtained from bleached pulp, DACwaq to dialdehyde lignocellulose obtained from pulp prepared by hot water extraction/kraft cooking, and DACw corresponds to dialdehyde lignocellulose obtained from kraft pulp.
