Influence of Sequential Acid-alkali Treatment on Palm Biomass Waste Properties

Palm biomass (Archontophoenix alexandrae) is a natural crop of the food industry, even with a high potential to produce sustainable and innovative products. Thus, the purpose of this work was to evaluate the effect of sequential acid-alkali treatment followed by precipitation with concentrated H2SO4 on fiber’s microstructure, chemical, and physical properties. So, the raw fiber, the pre-treated fiber, and the precipitated lignin were...
