Single item deacidification of paper with dispersion of magnesium hydroxide nanoparticles in alcohol: the problem of process efficiency
Journal Title: Annals of WULS, Forestry and Wood Technology; Zeszyty naukowe SGGW - Year 2016, Vol 96, Issue 1
Abstract
The aim of the study was to assess the efficiency of paper deacidification using magnesium hydroxide particles of nanometric dimensions. The techniques used included pH measurements of aqueous extracts, determination of the degree of polymerization (DP) of cellulose both for artificially acidified and iron gall ink- covered papers, and scanning electron microscopy (SEM) with SE and EDX detectors. From the analyses it follows that nanoparticles make it possible to obtain alkaline pH values of aqueous extracts of paper and reduce cellulose degradation, which attests to the effectiveness of the procedure. Following deacidification, deposits of magnesium compounds are mainly found on the surface of samples, however some nanoparticles are also seen to penetrate into voids within the paper structure.
