ABSTRACT

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 -13°C to form cellulose solution. The cellulose solution then was mix with magnetite (Fe3O4) nanoparticles synthesized via co-precipitation method of Fe2+ and Fe3+ in the presence of sodium hydroxide (NaOH) to form MCM. The MCMs formed at different percentage of Fe3O4 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 Fe3O4 nanoparticles increased. However, the addition of Fe3O4 nanoparticles in the regenerated cellulose membrane has decreased the crystallinity index of MCM. The surface morphology of the MCM showed that the Fe3O4 nanoparticles were dispersed in the pore of the membrane. Tensile test showed decreasing in the tensile strength of the cellulose membrane with the addition of Fe3O4 nanoparticle.

ABSTRAK

Dalam kajian ini, membran selulosa bermagnet (MSM) telah disediakan dengan menggunakan linter kapas sebagai sumber selulosa dan NaOH/urea sebagai pelarut selulosa pada kandungan magnetit yang berbeza. Selulosa dilarutkan dalam pelarut NaOH/urea yang telah dilakukan pra-penyejukan pada suhu -13°C untuk menghasilkan larutan selulosa. Larutan selulosa tersebut kemudiannya dicampurkan dengan nanozarah magnetit (Fe3O4) yang disintesis melalui kaedah pemendakan Fe2+ dan Fe3+ dengan kehadiran natrium hidroksida (NaOH) untuk menghasilkan MSM. MSM yang terhasil mempunyai peratusan Fe3O4 yang berbeza iaitu, 10, 20 dan 30 %. bt. Analisis daripada magnetometer getaran sampel (VSM) menunjukkan kemagnetan tepu bagi MSM bertambah apabila peratusan zarah magnetit meningkat. Walau bagaimanapun, penambahan zarah magnetit dalam membran selulosa terjana semula telah menjatuhkan indeks penghabluran MSM. Morfologi permukaan MSM menunjukkan bahawa zarah magnetit tersebar di atas liang membran tersebut. Ujian tegangan menunjukkan pengurangan dalam kekuatan tegangan membran selulosa dengan penambahan nanozarah magnetit.

 

Kata Kunci: Fe3O4; membran selulosa bermagnet; pelarutan; pra-penyejukan
