Abstract:
This letter discusses the discrepancies in thermodynamic studies in a recent article by Bouberka et al. Also presented is the significance of the separation factor R(L) used to express the essential characteristics of Langmuir isotherm. In addition, the incorrect forms of the two kinetics rate equations, the pseudo-first-order and pseudo-second-order equations used by the authors, are also mentioned.
