| dc.description.abstract | This project proposed coffee husk as a raw material for production of activated carbon using chemical activation process, the activating agent used in the activation process was phosphoric acid. The effects of various preparatory conditions including different activation temperature and pyrolysis time were investigated and characterized using proximate analysis to establish the optimum conditions for adsorption of methylene blue by activated carbons from textile industry waste. And the project focused on removal of methylene blue dye using activated carbon. Adsorption studies were carried out using methylene blue at different concentrations (2-10 mg/l), pH (1-10), adsorbent dose (0.4-1.2 g) and contact time (20-60 min). Studying through different graphs of pH, contact time, adsorbent concentration and Methylene blue concentration, the optimum values for each case at carbonization temperature of 600 oC; pH= 5; Contact time= 50 min; Adsorbent dosage= 0.8 gm; Methylene blue concentration= 20 mg/l. Finally the experimental data were fitted into both Langmuir & Freundlich isotherms and also show pseudo second order kinetics. Thus the activated carbon prepared from coffee husk could be used extensively in removal of methylene blue dye from waste water. | en_US |
