ENHANCED SELECTIVITY OF OXYGEN DELIGNIFICATION BY CHERRY AND GUAR GUM ADDITIVES

open access: yesCellulose Chemistry and Technology
Natural 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 ...

Efficient H2O2-system for fiber delignification-bleaching and its environmental impact

open access: yesDiscover Materials
Hydrogen peroxide (H2O2) is considered an eco-friendly oxidizing agent because it can decompose into water and oxygen in water. H2O2 has been implemented in the lignocellulosic delignification-bleaching through lignin degradation or dye by reactive ...
