Effect of lignin structure on adsorbable organic halogens formation in chlorine dioxide bleaching [PDF]

Royal Society Open Science, 2019
Adsorbable organic halogens (AOX) are formed in pulp bleaching as a result of the reaction of residual lignin with chlorine dioxide. The natural structure of lignin is very complex and it tends to be damaged by various extraction methods. All the factors
