In this study, investigate the changes occurs on the functional groups of biochar materials. The biomass materials subjected to the pyrolysis, which is a thermochemical conversion process to obtain biochar material. It was produced by slow-pyrolysis method by subjected in different pyrolysis temperatures (400, 600, 800 and 1000°C). Effect of the treatment procedures was determined by the modifications in the functional groups of the obtained bio-char during the pyrolysis treatment was determined with the Fourier transform infrared spectroscopy (FT-IR). FTIR methods deliver fast, low-cost and non-destructive analysis and have shown qualitative and quantitative outcomes. The analysis was applied to some agricultural biomass materials such as saw dust, rice hull, wheat hull, tea wastes, and eucalyptus shell. Results are associated with literature, and species potentially computable by Fourier Transform Infrared Spectroscopy are reviewed. The result showed that the aliphatic, hydroxyl and aromatic groups gradually diminishes by increasing the temperature from 400 to 1000°C.
