AbstractThermal behavior of sawdust, maize cob, and bagasse materials treated with basic dye was investigated using differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA). The results showed that the thermal decomposition pat-tent of both treated and untreated material has three peaks. The first peak is endothermic while the second and the third peaks are exothermic. The peak intensities and the corresponding temperatures differ for untreated and treated materials. The effect of treatment (adsorption of basic dye) was more pronounced for sawdust and maize cob than for bagasse. The calorific values of treated sawdust and maize cob are higher than the untreated. These materials are considered new potential source for energy conversion.
