Application of Chemical Oxidation Using Sodium Perioadate in the Production of Activated Carbon

In this work activated carbon of a good quality prepared using oxidation condensation process. The oxidation of the asphaltic materials was conducted using several percentage of NaIO4 and in the presence of a stream of air or oxygen. The reaction mixture was heated at 3 50C for 3hrs, this followed by removal of uncarbonized materials by heating under reduced pressure. The condensation of the fractions obtained is expected to recombine or re-react to give a high carbon content. The carbonization and activation was conducted at 55025C for3hrs. by mixing with NaOH, and the ratio of the feedstock to NaOH (1:2). After the carbonization was completed, the reaction mixture was subjected to purification by treatment with 10% HC1 and distilled water till it gives neutral test to the litmus paper. The samples were dried at 120C for 24hr. and its physical properties were determined. The research work indicated that a good quality activated carbon was obtained when the oxidation of sample was conducted using 3%
