Many papers deal with the characterization of various sorption supports, tested with numerous contaminants. However, the results concerning the same “sorbate/sorbent” system are often very different. In sorption studies, there are regularly misleading calculations concerning (i) both kinetic and isothermal modeling by linear (instead of nonlinear) equations; and (ii) calculation of thermodynamic parameters for sorption processes. It should also be noted that it is often impossible to compare the results of such studies and their interpretations. Indeed, according to the context of the studies (natural environment, wastewater, industrial system…), the experimental conditions are very different. Moreover, while studies could be dedicated to similar species, both sorbent and sorbate, the keywords associated to these papers can be different and authors can miss a published paper, making their bibliography incomplete. Therefore, we remind how to use correct procedures to perform these calculations in a valuable way; in our opinion, it is a source of confusion for the scientific community if inappropriate methods continue to be used. Moreover, we would like to encourage scientists to pay attention to the choice of keywords, and to suggest editors of scientific journals to increase the number of keywords. This is illustrated here with recent papers dealing with the sorption of P(V) on Fe(III) oxyhydroxides.
