| Abstract: | Summaries. Investigations have been made on the colour reversion of both ligneous and rag fibre papers bleached as follows-. pH 4.5 hypochlorite, pH 7.0 hypochlorite, pH 9.0 hypochlorite, chloramine-T, chlorine dioxide (immersion and gas methods), or stabilized hydrogen peroxide. The effect of anti-chlor (sodium thiosulphate or sodium borohy-dride) upon the rate of yellowing, as well as the possible influence of encapsulation of the paper artifact with 'Mylar' (polyethylene terephthalate) have been considered. The contribution of the extent of oxidation and chlorination of the cellulose and lignin components of the papers on the rapidity of colour reversion is discussed. Conclusions. |
