WebbWhat does it mean if non-linear form of Langmuir, Freundlich, and Temkin isotherms, are all precisely linear? My results for Freundlich nonlinear equation is: 1/n= 1.0166 and KF= 6.625 (since... WebbThis equation is converted into the Langmuir isotherm at equilibrium and describes well the unsteady-state adsorption process. Based on that, a working equation has been developed, which gives adsorption-rate-constant independent of operating parameters including concentration.
