The adsorptive behavior of WSAC was quantified using methylene blue as model
dye compound.
The best conditions resulted in activated carbon with a monolayer adsorption capacity
of 423.17 mg/g and carbon yield of 80.75%. The BET surface area, Langmuir surface area and total pore
volume were corresponded to 1496.05 m2/g, 2245.53 m2/g and 0.864 cm3/g, respectively.
The findings
support the potential to prepare high surface area and mesoporous activated carbon from wood sawdust
by microwave assisted chemical activation.
