In PUPAK: Parameter Estimation, and Plot Visualization of Adsorption Kinetic Models

Linear Boyd Intraparticle Diffusion Model

Description

The Boyd Intraparticle Diffusion Model is frequently applied to analyze if intraparticle diffusion governs the experimental kinetic data. This model assumes that the boundary layer surrounding the adsorbent has a greater effect on the diffusion of solute (Viegas, Campinas, Costa, and Rosa, 2014).

Usage

bid.lm(t, qt, qinf)

Arguments

t	the numerical value for contact time
qt	the numerical value for the amount adsorbed at time t
qinf	the numerical value for the amount adsorbed at infinite time

Value

the linear regression and the parameter estimation for the Boyd Intraparticle Diffusion model
