摘要

Deacidification is one of the basic restoration techniques to protect archival records stored in various depositories. This study examines the influence of selected deacidification aids on lignocellulose materials. Samples represent the commonly used pulps in the paper industry. These materials were treated with three deacidification methods in cooperation with National Archive in Prague. We monitored for changes as the optical, mechanical and chemical properties and changes on hypermolecular level. The results showed that the selected deacidification methods affect the surface-molecular and structural properties. The optical properties of the samples didn't show any decrease of the ISO brightness and the colour coordinates L*a*b*. The values of surface pH were increased as expected. The mechanical properties of the samples was characterised by unitary stiffness, it was observed a significant sample stiffness decrease after treatment with the Bookkeeper and HERCO deacidification methods.
