Investigation of activated carbon production facilities from sedge (Phragmites australis)

In this study, possibilty of producing active carbon was studied by using sedge. Purpose of study is obtaining active carbon which has good pore distribution, well adsorption feature and wide surface area by using sedge. As a liquid phase, area of using active carbon is removing organic contamination, taste and smell defect in home and endustrial waste water, various gas phase application and purification of chemical product. In this thesis, phosphoric acid (% 30, % 40, % 50 ve % 60 solution) and potassium hydroxide (% 10, % 20, % 30 solution) were prefered for activation prosess as activation agent. Degrees of 300 oC, 350 oC, 400 oC, 450 oC, 500 oC, 550 oC, 600 oC were applied for carbonization prosess. Methylene blue solution was used on test of obtained active carbons performances. Pore size distribution and pore volume were characterized by BET surface area measurement. Physicochemical properties were determined by using FT-IR analysis and SEM images. The optimum conditions determined in this study are 400 oC carbonization temparature and % 50 H3PO4 activation agent concentration to obtain best active carbon samples. Surface area of best powder active carbon sample which obtain optimum conditions is 654,620 m2/g.
