ADSORPTION ISOTHERMS AND THERMOCHEMICAL DATA OF FD&C RED N° 40 BINDING BY CHITOSAN (2011, methodology): “In this case, the Langmuir isotherm model can be more useful for describing the adsorption process of FD&C Red n° 40 by chitosan, due to the fact that the R-P isotherm parameters cannot be determined by linearization because it contains three unknown parameters (Wong et al., 2004) and that the Temki”
