Investigation Different cellulose resources for preparation of nanocellulose With the aim of extracting cellulose from wheat bran

The aim of this article is to review the recent researches on cellulose nanoparticle preparation from various resources. For this purpose, the materials were investigated in terms of their abundance, renewability, hardness, high resistance, biocompatibility and light weight. Different methods for separation of nanocrystals (from nanocellulose derivatives) were also examined. It was revealed that cellulose can be extracted by acidic hydrolysis from wood, fibrous plants of industrial and agricultural wastes . thenalpha-cellulose was extracted from wheat bran using chemical-mechanical procedure (Soxhlet – Ultrasonic waves). The chemical method involves lipid and wax removal with the prepared solvent (toluene-ethanol) and two-stage bleaching with a sodium chlorite solution. The mechanical stage was performed with the aid of an ultrasonic device to remove holocellulose (cellulose + hemicellulose). The alpha-cellulose was prepared for the first time at three initial times for 10 min, 30 min and 60 min. FTIR, DSC and XRD tested the effect of ultrasonic waves on the purification of the alpha-cellulose extracted from the wheat bran.
