【 摘 要 】

In Indonesia, membrane application is limited by the use of high cost imported membranes. Therefore, efforts to produce membrane using local materials are very important to be performed. Cellulose and chitosan are two materials, which their availability in Indonesia is abundant. In this work, cellulose acetate (CA) has been successfully produced from tropical water hyacinth via isolation and acetylation processes. By using FTIR, a comparative analysis of functional groups between the resulted CA and commercial CA was also investigated. The result shows that the IR spectra of the resulted CA and commercial CA are similar. The produced CA can further be processed into membrane. The resulting membranes were then characterized using SEM. In addition, the membranes were examined for filtering humic acid solution as surface water model. To improve the performance, CA membranes prepared from water hyacinth were modified by addition of chitosan (Chi) via blending in phase separation method. The resulting CA-Chi membranes were characterized using SEM and FTIR.
