Sunlight irradiation significantly mediates plant litter's carbon dynamics and volatile carbon
release in semi-arid and arid ecosystems. In this process, carbon loss is controlled by lignin …

Chlorine dioxide delignification (D0) modifies kraft residual lignin by oxidizing phenolic
groups to both quinonoid and muconic structures. Results from various in situ analyses (ie …

The kappa number test is a control parameter commonly used in pulp mills and bleach
plants for estimating the residual lignin content in brownstocks and partially bleached pulps …

Abstract Peroxide‐reinforced extractions ((EP) or (EOP)) of D0 pulps lower both post‐
extraction kappa numbers and Klason lignins more than either E or (EO). An oxygen …

The delignification of kraft pulp with sodium dithionite was studied to remove lignin content
in the pulp. The sodium dithionite dissolves the chromophoric groups and residual lignin …

Previously, it was shown that chlorine dioxide delignification (D0) modifies kraft residual
lignin by oxidizing phenolic groups to both quinonoid and muconic structures in∼ 2‐to‐1 …

Chlorine dioxide delignification (D0) modifies kraft residual lignin by oxidizing phenolic
groups to both quinone and muconic acid structures. Alkaline extraction (E), in addition to …

Kraft pulps delignified with ethanol-based chlorine dioxide (D0) stages yielded pulps with
higher brightness levels than aqueous D0 stages. However, when these pulps were …

The alkaline extraction stage plays a pivotal role in the residual lignin removed from the pulp
during Elemental Chlorine-Free (ECF) bleaching. The goal of this paper is to review and …
