ENHANCED SELECTIVITY OF OXYGEN DELIGNIFICATION BY CHERRY AND GUAR GUM ADDITIVES
Cellulose Chemistry and TechnologyNatural polysaccharide-based gums produced by plants in response to biotic or abiotic factors are used in various industries due to their biodegradability, renewability, biocompatibility, and non-toxic properties. This study examined the use of these gums in a new application, such as adding them to the delignification liquor to decrease the negative ...
