Olabimtan Olabode, Benedict Odjobo, Suleman Stephen.M Abstract: Crude glycerol as a by-product of biodiesel production is technical of low grade with significant levels of impurities in the form of carboxylic acids emanating from catalyst, alcohol, soap, and water. Selected parameters of the crude to treated glycerol with 12g activated carbon after acidification (12ml) with 1.19M sulphuric acid to the pH of 7 at 60OC for 30minutes with extra characterization (FTIR) reveal pH of 11.24 to 6.57, the relative density of 1.0504 to 1.2120, the refractive index of 2.4185 to 1.4540, the viscosity of 1026Cp to 940Cp, the water content of 9.27% to 0.23%, the ash content of 6.14% to 0.04% and the glycerol content of 15.56% to 95.96%. One parameter adsorption isotherm (Henry's model) was applied in the adsorption pattern of the crude glycerol impurities on the activated carbon with viscosity as an index of performance. This model supports the adsorption process by y=1.7833x - 1583.9 with the regression of (R2) 0.7731.
