Abstract
Cellulose is one of the most important natural biopolymers and as an inexhaustible raw material can be mentioned as an industrial scale biocompatible material. Cellulose can be applied in the form of wood and plant fibers as well as energy source and building materials and etc. By producing cellulose in cost-effective and environmentally friendly ways, a nanotechnology-based product can be produced with unique and particular performance. Therefore, it is expected that these products will be replaced with petrochemical products. Nanocellulose is made from lignocellulosic primary materials. In the primary years of the current century, a great deal of research in the subject of nanocellulosic material production and application has been started and going to be global as soon as possible. In the present study, the effective parameters on cellulose extraction from sugarcane bagasse were optimized using the Taguchi statistical method. The influencing parameters in the process of cellulose consists of delignification pH, dewaxation solvents ratio, Sodium chlorite concentration and pH of hemicellulose removal. An orthogonal array L9 has been chosen for parameter design. The structure of the extracted cellulose was confirmed by XRD and IR analyzes. It is noteworthy that the structure of the synthesized nanocellulose by application of FE SEM analyses was confirmed. Optimization of the cellulose extraction process by the Taguchi method showed that the importance of parameters on cellulose extraction was pH of hemicellulose removal, Sodium chlorite concentration, delignification pH, and dewaxation Solvent Ratio respectively.
