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.lm(t, qt, qe)

Arguments

t

the numerical value for contact time

qt

the numerical value for the amount adsorbed at time t. This parameter should not contain a value equal to zero as it will cause an infinite value. Any row(s) that contain(s) value of qt equal to zero will be automatically removed to proceed with the calculation.

qe

the numerical value for the amount adsorbed at equilibrium

Value

the linear regression and the parameter estimation for the Pseudo-Second-Order Model
