Abstract

Newspaper clippings tend to brown quickly with aging as the result of chromophores that form during the degradation of one or more components of paper. Newsprint that consists of approximately 40% lignin is particularly susceptible to browning due to the relative ease of the oxidation of lignin. For readers who wish to experiment with both whitening and deacidifying old newspaper clippings, a simple recipe requiring few materials is presented.

  Abstract:
  The inherent instability of old papers is largely due to the presence of acids which catalyze the hydrolytic degradation of cellulose. The use of alkaline paper can minimize the problem of acidity for new papers. This study focuses on the chemistry ...
