where qe is the uptake of dye, Ce is the concentration of dye in
solution, KF represents the Freundlich constant related to adsorption
capacity and n is the Freundlich constant related to adsorption
intensity (n > 1). Langmuir and Freundlich are known to be a twoparameter
isotherm, while the Redlich-Peterson model involves
three parameters. The model is used to find a compromised
