Mussel-Inspired Magnetic Dissolving Pulp Fibers Toward the Adsorption and Degradation of Organic Dyes [PDF]

Frontiers in Chemistry, 2022
In this work, a simple synthetic method was used to prepare a new type of magnetic dissolving pulp (MDP) @polydopamine (PDA) fibers. The hydroxyl groups of the fibers were converted into carboxyl groups after succinylation. Fe3O4 nanoparticles were grown

ALTERNATIVE PULPING PROCESS FOR PRODUCING DISSOLVING PULP FROM JUTE

BioResources, 2008
Dissolving pulps are the raw materials of cellulose derivatives and of many other cellulosic products. Jute is a very good source of cellulose and worthy of consideration for the production of dissolving pulp.

Valorization of Old Corrugated Container to Dissolving Pulp

BioResources, 2022
As an alternative raw material for various cellulose derivatives, the current research studied the processing of old corrugated container (OCC) in the subsequent stages of homogenization (soda cooking) and purification (bleaching with hypochlorite).

DISSOLVING PULP PRODUCTION FROM BAMBOO

BioResources, 2011
Commercial bamboo chips were evaluated as raw material for dissolving pulp production. The chips were auto-hydrolyzed (AH) and subsequently cooked by the NaOH/AQ process and bleached to full brightness with the O-CCE-D-(EP)-D-P sequence.

Cross-species comparison of ultramafic rock bio-accelerated weathering performance [PDF]

Scientific Reports
Carbon mineralization sequesters atmospheric CO2 by reacting it with cations from rock weathering to form carbonates. However, natural rates are too slow, and acceleration with chemical or mechanical methods is expensive. Microbial processes (acidolysis,

Enzymatic Fibre Modification During Production of Dissolving Wood Pulp for Regenerated Cellulosic Materials

Frontiers in Plant Science, 2021
The production of regenerated cellulosic fibres, such as viscose, modal and lyocell, is based mainly on the use of dissolving wood pulp as raw material. Enzymatic processes are an excellent alternative to conventional chemical routes in the production of

INVESTIGATION UPON DISSOLVING PULP

Sen'i Gakkaishi, 1958
Rayon grade sulfite pulp (RP, α-cellulose 92%), acetate grade sulfite pulp (ACP, α-cellulose 96%) and purified linters (Linters, α-cellulose 99%) were oxidized by ClO2 solution under the following condition : ClO2 (as avail. cl.) add. : 0-40% basis B. D. pulp, temp : 70°C, initial PH : 3-11 (unbuffered), and average D P, copper number, carboxyl content,

Kinetics of Viscosity Decrease by Cellulase Treatment of Bleached Hardwood Kraft-Based Dissolving Pulp

BioResources, 2015
A dissolving pulp of low cellulose viscosity represents a pulp of high quality; hence, it is often necessary to decrease the initial dissolving pulp viscosity.
