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
