Abstract
Synthetic melanoidin was produced from glucose-glycine system and was decolorized using titanium dioxide photocatalytic oxidation. This study was conducted by varying the pH, melanoidin concentration, catalyst dosage and solar concentration. Of the four parameters, the pH and melanoidin concentration had significant effects on decolorization according to two-way analysis of variance. At low pH, percent decolorization increases due to dominant attractive forces. At low pH, percent decolorization increases due to dominant attractive forces. At low melanoidin concentration, percent decolorization also increases due to increased solar light irradiation. Moreover, in the analysis of interaction effects, only the catalyst dosage - melanoidin concentration interaction had significant effect on decolorization. Separate control experiments were also conducted : adsorption by titanium dioxide and photolysis. The maximum percent decolorization obtained through adsorption of titanium dioxide was 17.18%, while the maximum percent decolorization obtained through photolysis was 1.05%.
