| Abstract: |
| [Objective] The preparation of fibrous inorganic materials with bagasse fiber as the template was explored to look for new method of high value utilization of bagasse.[Methods] Bagasse fibres were treated by alkali/peroxide, and the changes in the structure and ash content of bagasse fibers were studied in the extraction process of cellulose from bagasse.The iron oxide fibers were prepared by high temperature calcination with the different bagasse fibers as the template.[Results] The results revealed that the mean diameter of bagasse fibers, bagasse cellulose fibers and iron oxide fibers was 100~150μm, 10~30μm and 5~30μm, respectively.The ash content of bagasse fibers decreased in the process of alkali/peroxide treatment.[Conclusion] The fiber diameter and structure of bagasse fibers and bagasse cellulose fibers were significantly different in the transformation from bagasse fibers to bagasse cellulose fibers.The preparation of fibrous inorganic materials with bagasse fibers as the template is completely feasible and simple. |
