Rice straw may be used to produce alpha cellulose, according to research. Alpha cellulose was made by macerating rice straw with ethanol, delignifying with 3.5 percent sodium hydroxide, extracting alpha cellulose with 17.5 percent sodium hydroxide, and bleaching with hydrogen peroxide percent. In this work, the physicochemical properties of alpha cellulose were assessed and compared to earlier research. Cellulose is an organic substance found in plant cells, along with lignin. walls that aid in cementing the plant's structure Some of the physicochemical properties are: Scanning Electron Microscopy (SEM) was used to determine morphology, while X-ray Diffraction was used to determine crystallinity (XRD) analysis, Fourier Transform Infrared (FTIR) Spectroscopy of functional groups, loss on drying, pH as well as organoleptic. The SEM image depicts the morphology of cellulose fibres; the sample was semicrystalline, with a crystallinity index of 78 percent, and the functional groups in the sample were the same. Loss on drying was 8% w/w; pH was 7; and the organoleptic properties were the same as those reported in alpha cellulose.
