Résumé This study was conducted to evaluate the potential antioxidant activity of lignin
obtained from black liquor, a hazardous waste product generated during the extraction of …

Processes of extracting hemicellulose from annual plants usually neglect the cellulose
fraction. This study explored the possibility of obtaining both a hemicellulose and a cellulose …

A critical pathway towards enhancing pulp mill biorefineries is to integrate the extraction and
utilization of hemicelluloses into the pulping processes. Hence, an industrial pre-extraction …

Silica/lignin biocomposites were obtained by a new method proposed and fully
characterised. Silica was precipitated from aqueous solution of sodium silicate (as an SiO2 …

Lignin graft copolymer (LGC) was prepared using an addition polymerization technique that
involved grafting a 2-acrylamido-2-methylpropane sulfonic acid (AMPS) monomer onto soda …

The conversion of technical lignin into valuable chemicals is important for the complete
utilization of lignocellulose. The kraft process dominates the pulp industry, and large …

Inefficient separation of inorganic salts and organic matters in crystallization mother liquor is
still a problem to industrial wastewater treatment since the high salinity significantly impedes …

The lignin was extracted and purified by organic acid from pulping black liquor, and the
process and influencing factors of extraction and purification were studied. The results of …

Polypyrrole was chemically synthesised by using, for the first time, Birchwood xylan as
additive, and ammonium peroxydisulfate (APS) as oxidant. The impact of additive …

Coir pith black liquor obtained as a dark brown filtrate from oxidative delignification needs to
be decolourised before releasing to open environment. From this liquor industrially valuable …
