【 摘 要 】

The synthesis of biocomposites from rice husk (RH) fiber and magnetic nanoparticle was made by solvothermal reaction. Rice husk dried was blended to small size (60 mesh), then through delignification process to eliminate lignin by 1% w/v NaOH solution. Delignified rice husk was put into hydrothermal reactor, afterward was carried out by one-pot solvothermal at 200 °C for 6 h in the presence of 1,6-hexanediamine, FeCl3.6H2O and ethylene glycol. The process was produced two types of biocomposites, without amino group (RHB-M) and with amino group (RHB-MH). The characterization results shown by FE-SEM, magnetic nanoparticle have been formed on the surface of RH fiber with diameter size around 30-50 nm could be obtained. X-Ray Diffraction (XRD) analysis showed treatment of ED delignification was increased crystalinity index (CrI) about 16.77% and reduced silica content about 78%. The iron content may affect the adsorbent by enhanching the high-adsorption of sorbent capacity for reactivity toward a wide range of organic pollutan.
