Diffusion of zinc sulfate in agar gel medium

Diffusion of zinc sulfate in agar gel medium

Journal of Radioanalytical & Nuclear Chemistry 96(3): 233-240

The activation energy for the diffusion of ZnSO4 as a function of electrolyte concentration is computed by least squares fitting of the diffusion coefficient data obtained at various temperatures in the Arrhenius equation. It is observed that the activation energy decreases with increasing concentration of the electrolyte. This observation is accounted for on the basis of Wang's model. Further, the obstruction effect caused by the agar macromolecules in the diffusion path of ZnSO4 is also determined at these concentrations by varying the gel concentration at C. The obstruction effect expressed in terms of .alpha. a found to decrease with ZnSO4 concentration and explained on the basis of competitive hydration of diffusing ions and agar molecules.
