Abstract
Objective] The aim was to analyze element composition, cellulose content and crystallinity of 5 common net shells.[Method] Ac-cording to the height method, the tangent method, the peak area method, crystallinity of cellulose of net shells were analyzed by X -ray diffrac-tion (XRD).The composition and atomic ratio of the nut shell were studied by X ray photoelectron spectroscopy.[Result] The results showed that the crystallinity of cellulose in chestnut, peanut, sunflower, Hawaii nut and walnuts cortex were in varying degrees, the change was in the same tendency;X-ray photoelectron spectroscopy indicated that the shell of a nut was mainly composed of C , O, N, Si, and there were differ-ences in content.The crystallinity of Hawaii shell was maximum , and that of chestnut shell cellulose was minimum;N content in peanut was the highest, atomic percentage reached 3.78%, O/C and N/C ratio in peanut was maximum, respectively, reached 0.29 and 0.05.The Si/C atom-ic ratio was the highest in the peanut shell.[Conclusion] The results can provide basis for comprehensive development and utilization of hard shell.关键词
