Abstract:
Recent technological advances in water treatment point to the possibility of using membrane processes, such as reverse osmosis, to remove heavy metals from water, thus reducing operating costs of the system. The objective of this study was to produce membranes from sugarcane bagasse cellulose and use them in removing heavy metals from aqueous systems. Cellulose was isolated from sugarcane bagasse and passed for a stage of acetylation and, with the acetylated cellulose, the membranes were produced, first dissolving the material in dichloromethane and then, using two different methods to prepare the membranes: evaporation of the solvent (ES) and phase inversion (PI). The membranes were analyzed by SEM, flow of water permeation and retention of Cu2+ ions. Both membranes produced presented dense and homogeneous morphology. The membrane ES showed greater thickness than the PI. But they had higher weakness which prevented the determination of their flow capacity, because they broke early on in this test, whereas the membranes IF presented a water flow of 4.86 L/m2*h at 0.6 bar and 13.82 L/m2*h at 0.8 bar. Both membranes reached 15.0% of Cu2+ ions removal.
