摘要

这项研究对从两种红色海藻中提取的纤维素进行了比较，这两种海藻分别是蘑菇海苔和小马尾藻。用FTIR、XRD、TGA和SEM对纤维素进行了表征。研究表明，从H.musiformis和S.filiformis中提取的纤维素的特性相似。FTIR分析证实了这两种纤维素中都存在O-H和C-H键，而纤维素的XRD图谱证实了它们的结晶度，最大峰值在22°。在250至350°C的温度范围内，观察到了来自H.musiformis和S.filiformis的纤维素的热稳定性。用扫描电镜对两种纤维素的形态结构进行了研究，两种纤维素均显示出光滑的无孔表面。

EXTRACTION AND CHARACTERISATION OF CELLULOSE FROM RED SEAWEEDS OF Hypnea musciformis AND Sarconima filliformis

The study shows a comparison of cellulose extracted from two species of red seaweeds, namely Hypnea musciformis and Sarconima filliformis. The celluloses were characterized by FTIR, XRD, TGA and SEM analyses. The studies show similarities in the characteristics of the celluloses extracted from H. musciformis and S. filliformis. FTIR analysis confirms the presence of O-H and C-H bonds in the celluloses of both species, while the XRD patterns of celluloses confirm their crystallinity, with a maximum peak at 22°. The thermal stability of the celluloses from H. musciformis and S. filliformis was observed in the range of 250 to 350 °C. The morphological structure of the celluloses was studied using SEM and both celluloses showed smooth pore-free surface.
