Comments on the paper “Adsorptive removal of methylene blue by rhamnolipid-functionalized graphene oxide from wastewater”

Hereby, two mistakes of writing and applying pseudo-first order kinetic and Brunauer-Emmett-Teller (BET) isotherm models for adsorption systems have been pointed out. In this discussion, it is recommended and suggested to cite any kind of model e.g. kinetic, thermodynamic, isotherm, and so on from original papers of the mentioned models as well as a careful writing in order to prevent from repeating such inadvertent mistakes to publish more valuable and readable papers.
