Utilization of Ca(OH)2 nanoparticles in paper deacidification
Original language description
Deacidification is a process used for increasing pH value of papers in archives and libraries. Acidic paper thanks to acid hydrolysis of cellulose macromolecule becomes brittle over time, which are very unwished changes. Several technologies of deacidification process have been developed usually using solutions or particles with several micrometers size. Utilization of nanoparticles can increase the deacidification ability with less color influence on deacidified paper. In this paper, the utilization ofCa(OH)2 nanoparticles for deacidification will be described. Different types of Ca(OH)2 nanoparticles were prepared and characterized by XRD, SEM and TEM. The nanoparticles were prepared by reaction of calcium chloride solution with sodium hydroxide solution with at room temperature, in ultrasonic bath, with addition of alcohol and at elevated temperature (80°C). Also one type of commercially available nanoparticles suspension was tested. Consequently, ethanol suspension of these partic
