as a Renewable Lignocellulosic Biomass for the Synthesis of Cellulose Acetate and Glycidyl Methacrylate Grafted Cellulose.

High-grade cellulose (97% α-cellulose content) of 48% crystallinity index was extracted from the renewable marine biomass waste using H₂O₂ and organic peracids following an environmentally friendly and chlorine-free process. This cellulose appeared as a new high-grade cellulose of waste origin quite similar to the high-grade cellulose extracted from more noble starting materials like wood and cotton linters. The benefits of α-cellulose recovery from were enhanced by its transformation into cellulose acetate and cellulose derivative Fully acetylated was prepared by conventional acetylation method and easily transformed into a transparent film. with a molar substitution (MS) of 0.72 was produced by quenching Fenton's reagent (H₂O₂/FeSO₄) generated cellulose radicals with GMA. GMA grafting endowed high-grade cellulose from with adsorption capability. removes β-naphthol from water with an efficiency of 47%, as measured by UV-Vis spectroscopy. After hydrolysis of the glycidyl group to glycerol group, the modified was able to remove -nitrophenol from water with an efficiency of 92%, as measured by UV-Vis spectroscopy. α-cellulose and from waste can be considered as new materials of potential industrial and environmental interest.
