FT-IR and BET Characterization . FT-IR spectra obtained on the study of how the functional groups on granular activated carbon changed with increasing temperature are shown in Fig. 5.For the granular activated carbon produced at 300 °C, the weak peak observed at 1702.1 can be assigned to an unsaturated C=O group, strong peak at 1600.85 to an aromatic C=C group, .
Chemical precipitation or reagent coagulation precipitates impurities from purified water via change of pH, electrooxidising potential or coprecipitation using precipitating agents (coagulants) such as ferrous or aluminium sulphates (IAEA, 1992).Reagent oxidation is a special case of reagent coagulation in which oxidising reagents (e.g., potassium permanganate or .
