The adsorption of basic yellow dye on activated carbon from aqueous solutions under a centrifugal field was explored and interpreted by both a pseudo-first-order mechanism and intraparcticle diffusion mechanism. The adsorption process, based on the assumption of a pseudo-first-order mechanism, was developed to estimate the rate constant with the effect of centrifugal force, initial dye concentration. Also, the rate parameter based on the intraparticle diffusion model was presented. In addition, the diffusion coefficients were evaluated from both models. The results showed that the centrifugal force could enhance the rate constant, the rate parameter, and the diffusion coefficient. Therefore, better mass transfer could be provided with centrifugal force.
