Cellulose has been the extracted from rice husk by chemical treatment with aqueous solution of sodium hydroxide. The physical properties of derived cellulose (water uptake and swelling behavior) has been investigated with view of different applications. The morphology and chemical structure were investigated by Infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) and Thermogravimetry (TG) techniques. The results revealed the formation of homogeneous porous (micro size) membrane. Further, the UV-vis spectra of cellulose in different pH shows its responsiveness towards hydronium ion, which is suitable for drug delivery. Further, obtained cellulose was used for drug delivery under optimized pH.
