Diffusivity of Cu2+ in calcium alginate gel beads

Abstract

The diffusivity of Cu²⁺ in calcium alginate beads calculated by the shrinking core model (SCM) was reevaluated in this work. The results obtained in this work were significantly different than those by the original authors. There were excellent agreements between the results obtained by the SCM in this work and those by the more rigorous linear absorption model (LAM) by the original authors. © 1994 John Wiley & Sons, Inc.
