Non-Linear Pseudo Second-Order Adsorption Kinetic Model
Description
The Pseudo-Second-Order Adsorption Kinetic Model is an empirical rate equation known to be the simplified second-order expression of the Pseudo-First Order Adsorption Kinetic Model. It is widely applied to adsorption systems, from biomass to nanomaterials as adsorbent and from heavy metals to pharmaceuticals as adsorbate or contaminant (Revellame, Fortela, Sharp, Hernandez, and Zappi, 2020).
Usage
pso(t, qt, qe)
Arguments
t |
the numerical value for contact time |
qt |
the numerical value for the amount adsorbed at time t |
qe |
the numerical value for the amount adsorbed at equilibrium. If this parameter is not defined, it will be estimated. |
Value
the non linear regression and the parameters for the pseudo-second order non-linear model analysis
