Synthesization, Characterization and Application of Nano-Particles Ferric Oxide in Sodium Sulfide Oxidation

Sulfides usually found in the wastewater produced by chemical and petrochemical
industries such as tanneries, refineries, polymer industries. Removing sulfides from the
wastewater is currently a big challenge to the industries because sulfides are soluble in
water and various research and technologies have been studied and developed in order to
remove sulfides content. In this project, the author is focusing on removing sulfides
through oxidation process by using hydrogen peroxide as an oxidizing agent with the
presence of nano-particles ferric oxide as a catalyst. Nano-materials are increasingly
gaining the attention of the scientific community and also public due to their various
applications in the industries for example as a catalyst. In this project, author will
developed the procedure in preparing ferric oxide nano-particle as a catalyst and the
application of it in sodium sulfide oxidation process. Basically three stages are involved,
the synthesization, characterization and application. In application stage, the author will
study two parameters of the oxidation rate that is catalyst loading and sulfide
concentration. The effect of these parameters will be study by varying the variables for
these parameters. The results shows that after the more catalyst added, the oxidation
process increase by time and removal of sulfide can be achieve faster. The objectives
for this project are to successfully produce nano-particle ferric oxide as catalyst and to
apply it in the sulfide oxidation process.
