The adsorption of two dyes, namely, Basic Yellow 2 and Reactive Orange 16 on activated carbon from aqueous solutions under centrifugal field was studied. The results indicated that the centrifugal force could enhance the adsorption rate for both dyes. The data also showed that the centrifugal force could increase the adsorption rate with a higher degree for Reactive Orange 16 due to a lower mass transfer resistance. Consequently, the mass transfer for dye adsorption could be improved using the centrifugal force.
