Cellulose extractions from wheat straw via hydrochloric, nitric, and sulfuric acid hydrolysis methods were carried out. X-ray\ndiffraction spectral analyses reveal that depending on the acid conditions used the structure of the cellulose exhibited a mixture\nof polymorphs (i.e., CI and CIII cellulose phases). In addition, the percent crystallinity, diameter, and length of the cellulose\nfibers varied tremendously as determined by X-ray diffraction and scanning electron microscopy. Thermal gravimetric analysis\nmeasurements revealed that the thermal stability of the extracted cellulose varied as a function of the acid strength and conditions\nused. Scanning electron microscopy analysis revealed that the aggregation of cellulose fibers during the drying process is strongly\ndependent upon the drying process and strength of the acids used.
