Adsorption of Model Dyes Onto Porous Materials: Effect of pH and Temperature on the Parameters of Brouers-Sotolongo Kinetic Fractal and Generalized Isotherm

The goal of the present paper is to determine the physical signification of the parameters of the Brouers-Sotolongo fractal BSf(n, α) kinetic and the generalized Brouers-Sotolongo GBS isotherm in relation with temperature and pH of the medium. In both methods the fractal parameter “α” is related to the energy and geometry of the surface. The parameter “n” in the BSf formula is a fractional reaction order and the exponent “c” in the isotherm formula is related to the cluster or aggregation structure of the sorbent.
