Scanning Electron Microscopic Studies of Extracted Cellulose from Wheat Straw of Himachal Pradesh

Author(s): Swadesh Kumar* and Yogesh Kumar Walia

We utilize agricultural raw materials, wheat straw for the extraction of cellulose because wheat is grown-up in most of regions in India. Cellulose has been extracted, from wheat straw of different districts ofHima-chal Pradesh by TAPPI method, T-203-cm-99. The size and morphology of extracted celluloses were characterized by using the Scanning Electron Microscope (SEM). In SEM the structuresof extracted celluloses are displayed with their sizes and diameters on the micrometer scale. SEM micrographs of the Standard Cellulose (SC) (Cellulose powder pract, Central Drug House (p) Ltd. New Delhi) is compared with extracted celluloses of different samples andanalyzes onscale 10 μm. SEM micrographs obtained from different samples of extracted celluloses displayed that distribution of fiberdiameters ranging from 17 to 20μm. The micrographs of extracted celluloses show that the particles diameters are smaller than 20μm. Celluloses obtained from wheat straw shown more homogeneity in par-ticles size compared with SC.
