Non-Linear Pseudo-nth-Order Adsorption Kinetic Model

Description

The Pseudo-nth Order Adsorption Kinetic Model is an empirical rate equation known to describe the kinetic analysis of neither order 1 nor 2 kinetic parameters. It will have a significant effect on the calculation of the rate constants as the rate constant is dependent on the order of reaction (Tseng, Wu, Wu, and Juang, 2014).

Usage

pno(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 Pseudo-nth-Order Model
