Ramaiah Institute of Technology, Bengaluru-560 054, INDIA > Research Paper 2015 1 31 2015 March 18 In the current study, low cost activated carbon was prepared from the stem and flowers of widespread weed Tridax procumbens. Chemical activation method was used to prepare activated carbon; sulphuric acid was used as activating agent. The surface morphology was studied by field emission scanning electron microscopy. The variations in the functional groups were identified by means of Fourier transform Infrared analysis. Adsorption of environmentally hazardous anionic Eriochrome Black-T (EBT) azo dye onto the activated carbon was studied with various parameters such as effect of contact time, dosage, pH, initial dye concentration. From the result it reveals that the activated carbon prepared from Tridax procumbens is an excellent adsorbent for the azo dyes at lower pH. Copyright@ International Science Community Association
