Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part II. Experimental demonstration
(Elsevier, Amsterdam, 2009)
This paper demonstrates an experimental application of the nonlinear frequency response (FR) method extension to determine adsorption isotherms of binary mixtures. This method, based on the analysis of the response of a ...
Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part I. Theoretical analysis
(Elsevier, Amsterdam, 2009)
In this work adsorption equilibria of binary mixtures are quantified analyzing the nonlinear frequency response of a chromatographic column. Local partial derivatives of an isotherm model can be estimated for certain ...
