Radke-Prausnitz Isotherm Nonlinear Analysis

Description

The Radke-Prausnitz isotherm model has several important properties which provides a good fit over a wide range of adsorbate concentrations but more preferred in most adsorption systems at low adsorbate concentration.

Usage

radkeprausnitzanalysis(Ce, Qe)

Arguments

Ce	the numerical value for the equilibrium capacity
Qe	the numerical value for the adsorbed capacity

Value

the nonlinear regression, parameters for Radke-Prausnitz isotherm, and model error analysis
