ISOLATION OF NANOCELLULOSE FROM RICE WASTE VIA ULTRASONIC

Nooroddin Nazanezhad

Abstract


In this work, nanocellulose were extracted from rice husk and rice straw. Initially, the samples were submitted to different types of chemical treatment then the obtained purified cellulose fibers separated using from ultrasonication. Nanocellulose isolated by mechanical treatment has been characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Surface morphology and size of nanocellulose studies using SEM and AFM revealed that there was a reduction in fiber diameter during ultrasonication. XRD results indicated that the crystallinity of nanocellulose was approximately 62% and 71% for rice straw and rice husk respectively. The TGA curve of the isolated nanocellulose after ultrasonic treatment shown a degradation behavior is quiet similar to purified cellulose fibers, suggesting that the ultrasonic treatment had slight effect on the thermal decomposition of the nanocellulose.
