چکیده

Due to wide usage of nitrocellulose in civilian and non-domestic industries, massive amount of waste residues is generated. The waste has to be treated with an environmental friendly process. Historically, methodsfor decomposition of waste materials have been open burning or open explosion may not be suitable or safedisposal. Alkaline hydrolysis of nitrocellulose seems to be a simple and inexpensive method for cleavage of its structure to non-energetic materials that can be directly disposed or further biologically deteriorated. Furthermore having a valuable product is desired for making the process to be profitable. In this work, a simplemethod for alkaline decomposition of waste nitrocellulose to cellulose was used. The effect of sodium hydroxidesolution and temperature on decomposition of nitrocellulose was investigated. In such circumstances theoptimum conditions that achieved were 1.5 M sodium hydroxide, at 55°C. The identification and characterizationof product was carried out by Fourier Transform Infrared Spectroscopy (FTIR) and Scanning ElectronMicroscope (SEM). The obtain results showed that hydrolysis occurred and the product was completely denitrified and its characterization compatible and similar to pure cellulose.
