fiveparamanalysis: Five Parameter Isotherm Analysis

Description

A five-parameter empirical model that is capable of simulating the model variations that applies over a wide range of equilibrium data. Its increased parameters provides a more accurate non linear regression, better than two, three or four parameters. (Subramanyam and Ashutosh, 2009)

Usage

fiveparamanalysis(Ce, Qe)

Arguments

Ce

the numerical value for the equilibrium capacity

Qe

the numerical value for the adsorbed capacity

Value

the non linear regression and the parameters for the five parameter non-linear isotherm analysis
