This item is printed on demand - it takes 3-4 days longer - Neuware -Las muestras se recogieron en las montañas de Malakand, KPK, y se trituraron en partículas más pequeñas. Las muestras se extrajeron mediante el aparato Soxhlet con diferentes disolventes para eliminar el extracto soluble y las sustancias de cera. La celulosa cruda se trató en autoclave con sustancias alcalinas para romper los enlaces. La mayoría de las sustancias polares se eliminaron mediante EDTA y peróxido de hidrógeno. Además, las muestras se purificaron mediante una solución de ácido acético y ácido nítrico. La celulosa se neutralizó con agua bidestilada hasta obtener un pH neutro. La celulosa purificada se caracterizó mediante diferentes técnicas analíticas como la difracción de rayos X (XRD) que muestra una alta cristalinidad del 73%. El FTIR muestra la eliminación de diferentes grupos funcionales de la superficie. El TGA indica que la celulosa obtenida de diferentes fuentes de madera mostró que la pérdida de agua tiene lugar a 100¿C, la solubilidad extraída a 250¿C, y la lignina y la hemicelulosa a 350¿C. El SEM indica que la morfología y la forma de la superficie son poros muy visibles. La celulosa aislada tiene una alta cristalinidad, estabilidad térmica y buenas propiedades mecánicas. 96 pp. Spanisch.…
