英文摘要: Abstract(#br)Low-cost and effective activated carbon for copper ion adsorption was prepared from walnut shell by CO 2 activation in a fluidized bed. The effects of activation temperature and activation time on the specific surface area and yield were investigated. The adsorption performance of copper ion on walnut shell-derived activated carbons was examined in details. BET, SEM, FT-IR and XPS were used to determine the pore structure, morphology and surface chemistry of activated carbons obtained. Under the optimal condition (i.e., activation temperature of 900 °C and activation time of 90 min) the activated carbon with maximum specific surface area of 1011 m 2 /g and largest pore volume of 0.65 cm 3 /g with uniform micropores structure ( V micro / V Total was more than 80%) could be...
