The Effect of Dust Particles on Cellulose Degradation.
Bartl, B. ; Mašková, Ludmila ; Paulusová, H. ; Smolík, Jiří ; Bartlová, L. ; Vodička, Petr
This study focused on the changes in properties of cellulose-based paper Whatman 41, which can take place as a consequence of its contamination by dust particles. The chemical composition and size distribution of dust particles from archival repositories were analysed. After the artificial ageing, the viscosity-average degree of polymerization of cellulose DPv was measured. It was confirmed that cellulose-based paper can undergo substantial changes when contaminated by dust particles and artificially aged. The decrease of the DPv of cellulose showed a negative correlation with the deposited mass of sulfate ions in the dust particles. Considering the particle size fraction, the results suggest the decisive importance of the fine (PM1) particles. \n\n
