CHARACTERIZATION AND PROPERTIES OF ION EXCHANGERS PRODUCED FROM LIGNIN PRECIPITATED AFTER PEROXYACID PULPING

BioResources, 2008
Pulping of bagasse by one-stage and three-stage peroxyacetic acid was carried out. Characterization of the precipitated lignin from the waste liquor of the pulping process was studied using infrared spec-troscopy.

Influence of residual lignin content on physical and mechanical properties of kraft pulp/pp composites

Maderas: Ciencia y Tecnología, 2014
The effect of residual lignin content on the mechanical strength and water absorption of kraft pulp/polypropylene composites was studied. To meet this objective, hornbeam wood chips were converted to kraft pulp at three different alkalinities (15, 20 ...
