| Abstract: | Jute stick-based activated carbon are prepared by using jute sticks as raw materials and phosphoric acid as activating agent. The effects of several main factors such as concentration of activating agent, activation temperature and activation time on the yield and adsorption properties of active carbon are investigated via orthogonal experiments. Results show that the optimum conditions are phosphoric acid concentration of 2 mol/L, activation temperature of 400 ~C and activation time of 1 h. The yield is 42.93%, the iodine adsorption value and methylene blue adsorption value of the activated carbon are 1 059.26 mg/g and 353.10 mg/g, respectively. The specific surface area is 1 779.4 ㎡/g, the total pore volume is 0.960 m3/g and the average pore size is 2.16 nm, showing highly mesoporous structures. |
