Non-Linear Fractional Power Adsorption Kinetic Model

Description

The Fractional Power Adsorption Kinetic Model is an empirical rate equation in which the specific adsorption rate at a unit time can be estimated using its product's constant.(Netzahuatl-Munoz, Del Carmen Cristiani-Urbina, and Cristiani-Urbina, 2015)

Usage

fp(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 parameter estimation for the Fractional Power Adsorption Kinetic Model
