Flory-Huggins Isotherm Non-Linear Analysis

Description

Flory-Huggins isotherm model describes the degree of surface coverage characteristics of the adsorbate on the adsorbent. It describes the nature of the adsorption process regarding the feasibility and spontaneity of the process. The theory of the Flory-Huggins provides the mathematical model for the polymer blends' thermodynamics.

Usage

floryhugginsanalysis(Ce, theta)

Arguments

Ce

is equal to Co which is the numeric value for the initial concentration

theta

is the fractional surface coverage

Value

the nonlinear regression, parameters for Flory-Huggins isotherm, and model error analysis
