Abstrakt

In study of degradation products of paper, LC methods were tested for determination of some saccharides in water extracts of paper. Saccharides were analyzed by ion-exchange and partition chromatography with differential refractive index detection and on-line preconcentration, and by RP-HPLC with fluorescence detection based on pre-column derivatization with dansylhydrazine. The limits of determination for sugars (cellobiose, D-arabinose, D-fructose, D-galactose, D-glucose, D-lactose, D-mannose, D-xylose and methyl D-glucopyranoside) were evaluated by all the tested methods. The degradation products of paper after accelerated ageing for 0-30 days at 98 °C were estimated. The presence of some saccharides (D-mannose, D-fructose, D-arabinose and D-xylose) above the limits of determination was proved. Their concentrations depend on the type of paper modification and the ageing time.
