Preparation and Characterizaiton of Fe3O4/Regenerated Cellulose Membrane

TL;DRAbstract

In this study, magnetic cellulose membranes (MCM) have been prepared by using cotton linter as cellulose source and NaOH/urea as cellulose solvent at different magnetite content. Cellulose was dissolved in pre-cooled NaOH/urea solvent at -13C to form cellulose solution. The cellulose solution then was mix with magnetite (Fe 3 O 4 ) nanoparticles synthesized via co-precipitation method of Fe 2+ and Fe 3+ in the presence of sodium hydroxide (NaOH) to form MCM. The MCMs formed at different percentage of Fe 3 O 4 i.e., 10, 20 and 30%. Analysis from vibrating sample magnetometer (VSM) shows that the saturation magnetization of the MCM increase as the percentages of Fe 3 O 4 nanoparticles increased. However, the addition of Fe 3 O 4 nanoparticles in the regenerated cellulose membrane has decreased the crystallinity index of MCM. The surface morphology of the MCM showed that the Fe 3 O 4 nanoparticles were dispersed in the pore of the membrane. Tensile test showed decreasing in the tensile st
