✦ Synopsis
The adsorption kinetics of cephalosporin-c (CPC) on non-ionic polymeric macropore Amberlite XAD-16 resin were investigated in a well-stirred tank. The 'half-time' and non-linear methods were used to derive the intraparticle diþ usivities from the experimentally determined adsorption uptake curves. It was found that both pore and solid surface diþ usion processes made signiücant contributions, in parallel, to the intraparticle mass transfer. It was also found that the CPC concentration had an eþ ect on the eþ ective pore and surface diþ usivities. The results are relevant to the mathematical modelling of adsorption processes.
