Piecewise-Linear Weber and Morris Intraparticle Diffusion Model

Description

The Weber and Morris Intraparticle Diffusion Model is a multi-linear sorption process in which the intraparticle diffusion process is the limiting factor, where other interaction mechanisms such as adsorption on the external surface and diffusion into the interior may be happening simultaneously (Campos, Barbosa, Rodriguez-Diaz, and Duarte, 2018).

Usage

wam.pl(t, qt)

Arguments

t

the numerical value for contact time

qt

the numerical value for the amount adsorbed at time t

Value

the piecewise-linear regression and the parameter estimation for the Weber and Morris Intraparticle Diffusion Model
