| dc.description.abstract | Synthesis and characterization of activated carbon modified Fe3O4 has been
carried out by the hydrothermal method. This composite is made from coconut shell
activated carbon and a mixture of FeCl3.6H2O with FeSO4.7H2O. The work process
starts from the activated carbon activation stage using HNO3. Then proceed with the
synthesis step in a hydrothermal reactor that contains a mixture of activated carbon,
FeCl3.6H2O, FeSO4.7H2O, distilled water, and a little ethanol. The reactor is heated
at 250 0C for 5 hours. At the aniline adsorption tested, it used several parameters such
as pH, consentration, contact time, and weight.
The results of the characterization with FTIR showed the interaction of Fe-O
bonds on the wave number band 521.46 cm-1. The results of SEM-EDX show a
spherical surface morphology with a rough surface, XRD provides information that
this composite micro particle has a simple cubic structure.
This composite has succeeded in reducing the level of aniline in a dilute solution.
The trial results showed the optimum adsorption conditions at pH 5, 250 ppm
concentration, 75 minutes contact time, and 0.5 gram composite weight. | en_US |
