4b shows that in the multilinear plots of q t versus t 1/2 , there are intercept values of t 1/2 that are far from zero, which indicates that intraparticle diffusion is not the rate-controlling step of the adsorption process and that the external mass transfer may be significant in the rate-controlling step.
