Abstract
The activated carbon was produced from reed pulp lignin by precarbonization in the fluidized bed at 500°C for 5 min and followed by K2CO3 activation at 800°C in tubular furnace for 60 minutes. This separating process could produce carbon with micro, mesoporous structure and a large BET surface area of 900 m2/g. The adsorption can reach 266 mg/g quickly. The ratio of K2CO3 to the precarbonized lignin was 1:1. The Langmuir model gives the better fit than the Freundlich model in fitting the adsorption model of phenol. IR spectroscopy shows the presence of silicon and SEM shows the porous formation of activated carbon.
