RESEARCH ON SYNTHESIS OF MAGNETIC CELLULOSE FROM WASTE PAPER FOR OIL ADSORPTION

Tóm tắt

Modification of waste paper using NaClO as agent (6ml NaClO 2M) at
temperature of 35oC for 3 hours. The magnetic cellulose material was
synthesized by hydrothermal method with the ratio of Fe3+/Fe2+ = 2 (mol/mol)
corresponding to 100mL FeCl2 0.025M, 100mL FeCl3 0.05M and 40ml NaOH 0.5M
at 35oC in pH = 10 - 11. The results of differential thermal analysis (DTA) showed
that the magnetic cellulose sample was more thermally stable cellulose. The
thermal stability of the sample in the temperature range from 100oC to 500oC.
The SEM results show that the ability to disperse ferromagnetic particles very
well on the surface of cellulose fibers. The test results of oil adsorption of
synthesized materials showed that the material was able to adsorb 90.5% of oil
on the surface of water in 30 minutes at room temperature.
