Diffusion–adsorption problems in macromolecular systems: New techniques for parameter estimation


  • NCL Communication No. 4534.


It has been shown that the techniques used for estimation of diffusion–adsorption parameters in the past have certain basic flaws. New and efficient techniques for parameter estimation have been proposed. These have many advantages such as using the full concentration-time profile (rather than part of it), time saving, etc. The validity of these techniques has been demonstrated by the analysis of the data generated in our laboratory on adsorption of polyacrylamide and also the data on adsorption of dyes on chitin reported in the literature.
