kahnanalysis {PUPAIM}

Kahn Isotherm Non-Linear Analysis

Description

A generalized model recommended for pure solutions, in which both extremes, Langmuir and Freundlich, can be represented. This isotherm was developed to cater to both the single- and multi-component adsorption systems.

Usage

kahnanalysis(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value the absorbed capacity

Value

the nonlinear regression, parameters for the Kahn isotherm, and model error analysis
