The kinetics of sorption of aliphatic amino acids from aqueous solutions on clinoptilolite

Abstract

The kinetics of sorption of aliphatic amino acids glycine, valine and α-alanine clinoptilolite is
described on the basis of formal kinetic analysis, allowing to take into account the contribution of diffusion
and chemical stage. Installed two-stage nature of the sorption process. At the initial stage of the process
limits the chemical stage, the next stage is controlled nutrititional transport. The calculated values of the
kinetic parameters of the process. Earlier, the diffusion limit and a lower value of the effective diffusion
coefficient determined for α-alanine
